摘要
通过分析静止无功发生器、晶闸管投切电容电路、SPLL等效原理图,提出了混合式动态无功补偿装置的拓扑。利用坐标变换法建立了同步旋转坐标系下的数学控制模型;完成了Simulink下的建模仿真,并给出了210 kvar装置的电容配置参数。设备现场运行验证了该装置在提高功率因数、无功补偿方面具有良好的性能和应用价值。
This paper analyzed the static var generator, thyristor switched capacitor circuits and SPLL equivalent schematic diagram, and presented the topology of hybrid dynamic reactive power compensation device. The mathematical model of the synchronous rotating coordinate system was established by using the coordinate transformation method. The Simulink modeling and simulation were finished, and the capacitor configuration parameters of 210 kvar device were given. The operation of the equipment was verified by the device, which has good performance and application value in improving power factor and reactive power compensation.
