In the power equipment of modern enterprises, most of the inductive loads are used, which makes the production process generate a large amount of reactive power. Because reactive power not only increases the line loss and equipment capacity of the power system, but also causes fluctuations in line voltage, so it has a serious impact on the power quality and power supply efficiency of the power sup...
The basic principle of the intelligent Hybrid Static Var Generator is that the Static Var Generator, the capacitor bank and the reactor bank together form a reactive power compensation system. The static var generator performs fast and high-precision reactive power compensation. The Capacitor Banks performs slow and stepped reactive power compensation. The intelligent Reactive Power Hybrid Compens...
1.Introduction of YT Hybrid Static Var Generator System Static Var Generator + Capacitors Hybrid intelligent Reactive Power Compensation device adopts the configuration scheme combining static var generator and switching capacitor/reactor. According to the actual needs of users ,it can implement different reactive power compensation schemes to achieve the best combination of price and effec...
Characteristics of reactive energy Reactive energy is not consumed, it is not useful for the system. Although it does not produce useful work, it is necessary to neutralize or compensate it. The reactive energy is measured in kVArh (Kilo volt-amp reactive hour). Reactive energy is created in devices or machinery that works with motors or transformers powered by the alternating current that reaches...
The History Of Reactive Power Compensation If you are in the power industry, you must have heard of reactive power compensation. But you may not know much about it. What is reactive power compensation? We know that the power output of the power grid includes two parts: first, active power: directly consume electric energy, convert electric energy into mechanical energy, thermal energy,...
Power Quality Problems Residential community power grids are low-voltage power distribution networks, generally connected to large power grids by 10/0.4kV transformers. Most of the loads in the grid work at three-phase 480V and single-phase 220V voltage levels, mainly small-capacity loads, such as air conditioners, refrigerators, and televisions. Machines and other household appliances. Most house...
Power cabinet The complete power distribution device is a complete set of devices supplied by the manufacturer. According to the requirements of the main wiring, the manufacturer assembles the electrical equipment of each circuit, including control appliances, protection appliances, measuring appliances (such as circuit breakers, disconnectors, mutual inductors, etc.), bus bars, current carrying c...
Introduction To Capacitors And Reactors Reactance includes inductive reactance and capacitive reactance, and reactor includes inductive reactance (inductor) and capacitive reactance (capacitor). Inductance has the function of "blocking AC and blocking DC", that is, in the AC circuit, the characteristics of inductive reactance are used to "pass low-frequency DC and block high-frequency AC". The cap...
