指出了无功补偿的目标。用旋转矢量法和演绎法对电路进行分析后得出结论:为达到补偿目标,补偿器应是一个可以快速控制的无功网络,固定电容器与晶闸管控制的电抗器并联,能构成符合要求的网络。用对称分量法导出了补偿电流同负荷电流的关系式,进而运用复功率的概念导出了补偿电流同负荷无功功率的关系式,并以后一种补偿规律表达式为基础,提出了控制系统的结构,简述了几个环节的工作原理。
Pointed out the goal of reactive power compensation. The analysis of the circuit using the rotation vector method and the deduction method leads to the conclusion that the compensator should be a fast-controllable reactive network to achieve the compensation target. The fixed capacitor is connected in parallel with thyristor controlled reactors to form a network that meets the requirements . The relationship between the compensation current and the load current is deduced by using the symmetrical component method, and then the relationship between the compensation current and the reactive power is derived by using the concept of complex power. Based on the compensation law expression, the control system Structure, briefly describes the working principle of several aspects.
