中文摘要:

提出了一种通过晶闸管开关装置直接调节电容器两端电压以调节电容无功功率的方法,介绍了该方法的原理及接线。对10kV小容量的补偿装置进行了一些主要设备参数的计算,还提出了换级控制方法,并利用MATLAB/Simulink对换级过程的有关电压和电流暂态特性进行了仿真分析,结果表明：补偿装置能多级、大范围调节容性无功,换级控制暂态性能良好,较之于其它快速补偿装置综合工程造价低,有望用于高压电网。

英文摘要:

A method for reactive compensation by using thyristor switching device to change the capacitor voltage directly and the wiring of the principle are proposed. The main calculations for a number of 10kV small capacity device’s parameters and the tap-changing control method are also analysised. Conducted a simulation by MATLAB/Simulink for the transient characteristics of corresponding voltage and current in the tap changing process, indicating that the device can adjust capacitive reactive power in multi-stages and large scale, transient performance in grade-changing process is good. The project costs lower than other fast reactive compensation devices,and this equipment can be widely used in high voltage power network..
