Energy Resource Saving 

The economic, political and military development of industrial countries are more and more depend on presence in necessary quantities of the energy resources. The energy resources become the same universal money's worth, as well as gold. Today, not only financial well-being of the separate companies and countries depends on it, but the environment and survival of the citizens of these countries in nearest 20 years depends on it. 

The development of the new methods of energy saving is the most priority direction of scientific researches.

China,  India and countries of South East Asia, are promptly developing the industry. Today the volume of consumption of energy resources in these countries competes with that of the USA and European countries.

Global consumption of natural energy resources and their price steadily grows. The production, transportation and processing of natural energy resources are accompanied by numerous failures and ecological accidents.  Fear of ecological death of all mankind does not delay the development of industry.

In a severe competitive struggle, the winner is the one who, by manufacturing similar products, consumes less electric power. The complete development of energy saving technologies is the main objective of a modern science and practice. Methods of achieving this purpose can be different. But only the one who will proceed with energy saving technologies faster, will become the winner.

The analysis of define the most effective methods of energy efficiency. The purpose of such analysis is the block diagram of manufacturing and its current consumption, will allow to qualitative estimation of the weight importance of each link of the block diagram. It will allow the choice of a priority in the direction of development of energy saving technologies in different industries by criterion: the minimal investment of monetary resources to the maximal increase of efficiency.


 1. POWER STATION. It is well known that about 75 % of all electric power is developed by thermal turbines of power stations. The thermal power station processes natural energy resources such as petroleum (black oil), gas, coal, and peat into electric power. The EFFICIENCY of transformation of natural energy resources into electric power by thermal turbine makes 21%.

The total EFFICIENCY of power stations is about 70 % at the expense of additional beneficial use of pair and hot water. In the given analysis it is important to know with what efficiency natural energy resources to electrical energy will be transformed. EFFICIENCY = 21 %.  It is also very important to understand, that gas, coal, petroleum (black oil), and peat - are not renewable energy resources on the Earth. 

2. STEP-UP SUBSTATION.   Raising transformer substation: EFFICIENCY = 98 %.

3. TRANSMISSION FACILITIES. High-voltage lines connecting power stations with the industrial consumers of the electric power. The total losses in the country achieve 4 % - 6 %. EFFICIENCY = 95 %. 

4.  STEP-DOWN SUBSTATION.  Decrease transformer substations: EFFICIENCY = 98 %.

5. ELECTRIC DRIVE.  Drive: from 60 % up to 70 % of all made electric power is consumed by asynchronous three-phase electric motors. Let's view them in more in detail.

 Theoretically and under the passport, in the nominal mode of operations the asynchronous engines have high EFFICIENCY = 80 % - 95 %. Such a mode of operations is really possible to artificially create in laboratory conditions.

In real conditions of operation, practically none of the asynchronous electric motors work in a nominal mode.

First, because the asynchronous electric motors have an unsatisfactory (nasty) mechanical characteristic: this is the dependence of the frequency of rotation of the shaft of the engine and moment. The starting moment is small, and 95 % of a high-speed range of the characteristic is unstable (instability failure). For this reason, the speed of the asynchronous electric motor is not adjusted to one parameter - voltage or current, but 99 % of all technological operations require regulation.

Second, the small starting moment results in the designers and  experts of operation of the electric equipment to overestimate the established capacity of the asynchronous electric motors by 1.5 - 2 times, and in case of heavy start-up even by 3 - 4 times. It results in a decrease of reliability and essential losses of the electric power. After the start-up of the equipment, as a rule, there is a fall of loading and the engine gets into an area of low EFFICIENCY.

 Third, if there are enough start-ups and stops at one o'clock, depending on the direction, the EFFICIENCY of asynchronous engines essentially falls.

Fourth, the long work in addition to small loadings reduces EFFICIENCY.

 And finally, the voltage reduction in an electrical network and a bad quality of energy, which can be caused by the practice of various technological reasons, reduces EFFICIENCY. The asynchronous electric motor requires precisely rated voltage.  The downturn of a voltage in total of 5 % can result in failure.

With complex and responsible technological equipment, control systems and regulations of speed can be established as devices of protection of the electric motor. It essentially raises the cost of equipment. That is why the adjustable electric drives make less than 10 % of the general number of used asynchronous electric motors. Millions of the consumers use non-controllable asynchronous electric motors.

Usually, experts do not trouble themselves with checking of real EFFICIENCY of asynchronous electric motors. And this is vain. It is convenient to think, that the efficiency is such, as is specified in the passport. They forget that it happens only at nominal loading, rated voltage, and ideal sine wave form of a voltage. In such conditions no technological equipment can work.

For these reasons, over a period of time, about one month or three or more, the average meaning of EFFICIENCY of asynchronous engines in view of work with small loading, in a mode of start-up, stops, varied on a direction etc. in various branches of a national economy is in a range of 12 % up to 30 %.

For example, direct measurements of EFFICIENCY of the submersible asynchronous engine for oil-extracting on a real oil-well have shown the meaning of EFFICIENCY within the limits of 18 % - 22 %, though in laboratory on the simulator this parameter made 75 %. This is not because of bad submersible electric motors or personnel the matter in Russia. The American experts working in Russia know that Russia has very good specialists.

The asynchronous electric motors however, do not work in a nominal mode.

Let's return to our calculation of real efficiency of transformation natural energy resources into useful work. We accept in accounts average EFFICIENCY of asynchronous electric motors 30%. Dont be surprised, even this is a high meaning.

6. MACHINE TOOL.  Working machine intended for transformation of electrical energy to useful work. Working machines (process equipment) in nominal conditions can have high EFFICIENCY, down to 80 % - 90 %. However, practically all technological operations require regulation of working parameters. With the absence of regulations, the EFFICIENCY of the working machine is reduced to 30 % 40 % We accept EFFICIENCY = 40 %. 

The existing controls systems of asynchronous electric motors allow the adjustment of frequency of the rotation of the shaft of the electric motor and accordingly optimize work of the processing equipment have expensive costs. Besides, they require constant presence of highly skilled attendants. In addition it increases financial expenses. Therefore, the share of adjustable drives does not exceed 10 % and in accounts they can be neglected.

Let's count now the efficiency of transformation of natural energy resources in the useful operation. For this purpose, we shall multiply EFFICIENCIES of all basic making block diagrams in relative units.

Total EFFICIENCY = 0,21 * 0,98 * 0,95 * 0,98 * 0,3 * 0,4 = 0,02. Only 2 %!  

 Nearly 98 % of potential natural energy resources turn to a poisonous smoke and heating of the environment! The transformation natural energy resources in useful operation in an industry and agriculture occur on 2 %. 

The figures, used in accounts, can differ from what you use. It depends on sources of the information. Strength of the given analysis is that, it does not influence accuracy of the received result.  Really, millions of consumers use non-controllable asynchronous electric motors. It is the fact. The uncontrollability of asynchronous electric motors brings in the determining contribution to power inefficiency of the use of natural energy resources.

Does this not explain the basic reason of shortage of energy resources and approaching global power crisis? All this is also accompanied by numerous ecological problems in different parts of the world. What to do?

Best practices in energy management.

    How can we raise the effectiveness ratio at a minimal investment of means? Obviously, it is necessary to choose a priority direction by criterion: the minimal investment of monetary resources to the maximal increase of efficiency. Let's make one more analysis.

  * THE EFFICIENCY of the thermal turbine of power station theoretically is possible to rise on 1.5 %. It requires huge monetary investments and of extensive work in scientific research institutes and experimental manufactures. It is expensive and long.

  * THE EFFICIENCY of transformer substations can be lifted on 1%, but it too will require large capital investments and extensive time.

  * To raise EFFICIENCY of high-voltage lines it is possible on 2% - 3% at the expense of the introduction of new technologies, for example the use of lower temperatures, etc. The work requires huge capital investments and will also take a long time.

  * EFFICIENCY of the asynchronous electric drive and a working machine has dependable EFFICIENCY, therefore, as a parameter of efficiency it is necessary to consider their products.

We offers energy saving solution that can be implemented right away.

Nikolai Vasilievich and Sergei Nikolaevich Yalovega have thought up energy saving electric motors of an alternating current named RPEY. How is it possible to solve a problem of ENERGY EFFICIENCY with the help RPEY? 

The task can be solved by simple replacement of existing asynchronous electric motors with RPEY. Numerous research studies in real conditions of operation have shown that RPEY, at performance of the same work as asynchronous electric motors, consume two to three times less electric power.

Strength of the given solution is that it does not require huge monetary investments and extensive years of work. Such a replacement can be made on the existing equipment by simple modernization of asynchronous electric motors.  

This means modernization, but what does it offer?

  The design of the electric motor is kept complete. The technology of its assembly remains in its former form. There is no need to retrain the personnel and to equip manufacturers with new machine tools and equipment. RPEY is made in a design of the traditional asynchronous electric motor. It keeps all the positive properties, including high power parameters in the nominal mode of operations, besides that, there are new unique properties:

1. RPEY is adjusted at a constant frequency of a current with a smooth change of size of voltage in all high-speed ranges. In result, millions of consumers have the appearance of adjustable energy saving electric motors externally that are not distinguishable from the asynchronous electric motor.  It is not difficult to install RPEY into the existing equipment.

The regulation of frequency of rotation of the shaft in RPEY is provided with auto transformers which are simple, reliable, and accessible in price. They can be hand-operated or by a remote control. This does not require highly skilled attendants. In those cases where attendants are required, exact regulations and application feedback are provided with the simple design of semi-conductor regulators of voltage.  The consumers will receive inexpensive control systems.

2. RPEY has a steady range in all mechanical characteristics. The starting moment is maximal and it is 2 - 3 times more than with asynchronous electric motors. Even in the event of heavy start-up of equipment, RPEY can be applied without excess of the established capacity. Therefore, the RPEY motor always works in the field of high EFFICIENCY.

3. In the event when there is not a place with nominal loading, the EFFICIENCY of RPEY is reduced considerably. Therefore, even in a non-controllable drive, when loading frequently varies, the RPEY is 2 or 3 times more economic than asynchronous engines.

4. With fluctuations of voltage, including a decline some times, and not "overturns", as with the asynchronous electric motors, RPEY steadily works with a smaller capacity, but at the same time with a higher EFFICIENCY. For this reason, the safety in operation and the average (on a long interval of time) of EFFICIENCY has been raised.

5. For this reason, the smooth start-up, without impacts on the connected machine, is provided. The heating of the electric motor during frequent start-ups and stops is reduced resulting in reliability and the between-repairs resources to rise. The cost for the service of technological equipment as a whole is lowered.

6. The critical overload of the engine is accompanied by a smooth decrease of frequency of rotation of the shaft of the electric motor. The critical moment and sudden stops of the electric motor are absent. For this reason, safety in operation of the engine and the connected working machine raises. The allowable number of start-ups and stops during the given time and in special modes is increased.

 7. The dimensions and weight of the electric motor, in comparison to the asynchronous electric motors of similar capacity, are reduced by 25 % - 100 %. Thus the location of fastening of the asynchronous engine of a similar capacity and purposes are kept.

RPEY will be ideal in situations when the equipment does not allow for an increase in dimensions of the electric motor, and the large capacity is necessary, for example, in case of the submersible electro-pump equipment for oil-extracting.

The RPEY is much more powerful than asynchronous electric motors, allowing expanding borders of application of such equipment. Short and powerful submersible RPEY are convenient for using strong curved gas or oil wells. The RPEY average EFFICIENCY = 70 %

We would like you to note that we offer the most simple of all known methods of regulation by the electric motor of an alternating current and simultaneously the most reliable and inexpensive. Besides, at regulation of amplitude of voltage by the auto transformer, the quality of energy is always much better than at regulation by semi-conductor frequency regulators (on a basis thyristors or transistors).

One more very important property of the three-phase oil transformer is its lasting reliably to work in heavy climatic conditions: sharp daily differences of temperature, conditions of high elevation, of sea tossing, etc. The EFFICIENCY of the adjustable working machine is equal to 80 % 90 %. We accept EFFICIENCY = 80 %. 

Let's count now efficiency of transformation of natural power resources:

Total EFFICIENCY = 0.21* 0.98 * 0.95 * 0.98 * 0.7 * 0.8 = 0.10.

10 % instead of 2 % is turned out. This is 5 times more economical!

We can raise efficiency of transformation of natural power resources by 5 times only at the expense of modernization of all asynchronous engines. Consumers can reduce the consumption of electrical power by 5 times in engines already existing in the industrial and agricultural areas.

Even if in practice the real consumption would to be reduced not by 5 times, but by 2 times, it would still be a huge improvement in the area of ENERGY EFFICIENCY. It is excelent engineering solutions. The unused electric power can be directed to developing industrial needs without the additional damage to ecology and the environment, besides saving billions of dollars of profit.

We offer a ready solution that can be implemented right away for the global problem facing mankind, a problem of shortage and rising costs of energy resources. This modernization immediately offers large economic benefits. The novelty of technical solutions in the form of Energy Saving Resources is confirmed by patents from Russia, USA, Canada, Austria, Germany, France, Great Britain and  Italy. We really have a very good solution for the problem of  Energy Resource Saving.
