In the evolution of China's modernization construction at present, the development of electric power has become one of deciding factor of socio-economic development.GDF in China, in the propagation process, therefore the too high China's rapid economy development that had influence on of the energy consumption of per GDP develops the basic principle that electric power and saves energy will become China's long-run development from now on.
At present, all exist more energy waste phenomenon from electrical network conveying, block supply to the terminal temperature difference group.The first, the power station is the circuit loss of avoiding in the long distance power delivery process, transmit with higher voltage, reaches rated voltage to guarantee terminal temperature difference, causes virtual voltage often to be higher than the rated voltage of user's request.Second in the scope of block supply, promptly in the Mo Duan customer group, because the situation difference that goes into operation, has only the user of 70-80% carrying 100% supply of electric power usually, causes the dispensing capacity of electric power further superfluous.The 3rd, motor for a certain concrete unit, equipment operate as normal when guaranteeing peak of power consumption often require the output voltage of transformer to be higher than the rated voltage of motor, and because the lazy weight that goes into operation of most of unit causes the further surplus of its rated capacity again.Therefore in the running of this supply network, usually cause the power consumption of motor and the serious energy between the power supply amount of power supply state that do not match.Especially when motor is in zero load, underloading and moderate load, the situation of not matching of this energy will be more outstanding.
In order to solve the waste of energy problem of above-mentioned power consumption equipment, promptly begun Research on energy saving from 1840s abroad, China has also carried out corresponding power-saving technology research in the initial stage sixties in last century.Experienced the development in 60 years, up to the present, polytype power-saving technology and energy-saving device have successively appearred, as capacitance compensation, star angle conversion voltage regulation, single-circuit transformer step-down, silicon-controlled voltage regulation, computer control step-down, reactor pressure regulation, inversion pressure regulation, harmonic wave and a series of power-saving techniques such as surge current inhibition and frequency control.But up to the present, these a series of power-saving techniques require very inapplicable for many running status economize on electricitys of motor, as be operated in heavy duty, fully loaded and overload condition following time (its load is respectively 80-90%, 90-100%, 10 and foretells 135%) when motor, when the power factor of motor operation is higher (0.65-0.98), when constant load and permanent torque motor are operated in heavy duty, fully loaded and overload condition following time or the like.And the quantity of the motor of this operating state and operation conditions accounts for society and has about 80% of motor total amount, so power-saving technology must be sought new breakthrough.
The electromagnetism regulation and control are the developing a kind of new methods that are used to regulate and control the electric current and the voltage swing of load (motor) of power-saving technique in modern age, and the reliability of its regulation and control and accuracy have determined the power saving rate of energy-saving device and the range size that is applicable to the economize on electricity field.Its basic principle is, utilizes both effects of restricted electric current of inductance, the characteristic of consumed power not again, and with the critical component of inductance as power conversion, when power connection, inductance converts the electric energy that absorbs to magnetic field energy and is stored in the magnetic field.In certain running section, magnetic field energy rises along with the increase of electric current, and reaches maximum, and in other running section, magnetic field energy progressively reduces again, and quickly falls to zero, and the original magnetic field energy that stores is returned power supply again in the inductance.The present invention utilizes this principle exactly, by the line design of science, and the accurate Calculation of various operational factors, in the intellectuality control of computer, realized effective power saving rate of battery saving arrangement.
