摘要
根据TSC能够提供大容量的容性无功容量,实现无功功率的粗略补偿,STATCOM能够提供小容量的感性与容性无功容量,实现无功功率精确补偿思想,设计了基于STATCOM与TSC协同运行的混合无功补偿装置。首先提出了混合无功补偿系统的电路结构,通过选择TSC支路结构、电容器分组方法与STATCOM间接电流控制策略制定了该装置的工作方案。接着通过对TSC电容器、电抗器与晶闸管的参数选择,设计了总控制器控制方案。最后搭建了TSC+STATCOM装置的控制模块与主电路,对TSC+STATCOM装置投运电网系统前后进行了仿真,仿真结果验证了TSC+STATCOM无功补偿装置在提高功率因数、抑制自身谐波含量、稳定系统电压等方面均能达到理想的效果。
With the aid of both TSC's large capacitive reactive power capacity, and STATCOM's emotional and small capacitive reactive capacity to achieve reactive precise power compensation, it designs this reactive power compensation device based STATCOM and TSC collaborative mixed operation.Selecting the TSC branch struc-ture and the capacitor grouping STATCOM indirect current control strategy, it develops a program of work of the device, proposes a hybrid system reactive power compensation circuit configuration.Aiming at the parameters such as TSC capacitors, reactors and thyristors, it designs the overall controller program.Finally it builds TSC+control module and main circuit of STATCOM devices, simulates the operation feature before and after putting the TSC+STATCOM devices into the grid system, proves that the TSC+STATCOM reactive compensation devices can improve power factor, suppress harmonic content itself, stabilize the system voltage, achieve the desired effect.
