摘要
阐述了一种以交-直-交电路为主体的新型无功补偿装置的工作原理,基于无功功率的物理意义,提出了通过改变电压激励形式使同性负载之间相互无功补偿的可行性。补偿的关键在于相互补偿的负载之间存在能量交换。通过仿真实例电路的电压、电流波形和瞬时有功功率、瞬时无功功率波形,论证了补偿结果。最后得到感性负载可以通过改变电压激励的方法实现对系统感性无功进行补偿的结论。
The principle of a new type of reactive power compensation equipment is explained ,which is mainly made of a sort of AC - DC - AC circuit.Based on the physical signification of reactive power ,it is feasible that two loads with same character may compensate each other through altering the compensating voltage ,the essences in which is the exchange of power between two loads.The effect of compensation is testified by the voltage waves ,current waves ,instantaneous active power waves and instantaneous reactive power waves ,which come from the simulation of a concrete circuit.The conclusion is that an inductance can compensate inductive reactive power in power system through altering compensating voltage.This project is supported by Key Technologies R&D of Guangxi Province ( 0322014-4 ) .
