| 摘 要： | 针对电网无功功率实现动态无功补偿的问题,采用模块化的设计方法,设计出一种基于DSP的D-STATCOM电路。根据瞬时无功功率理论计算参考电流和补偿电流,并采用直接电流控制方法产生补偿电流。建立了整个补偿过程的数学模型,分析了D-STATCOM中电流控制算法、电压控制算法以及IGBT晶闸管通断时间控制算法。结果表明:D-STATCOM完成无功补偿,达到抑制谐波的目的。

| Abstract: | In view of dynamic reactive power compensation in electric power systems,with modular design method,a circuit of D-STATCOM base on DSP is designed.According to instantaneous reactive power theory,reference current and compensation current are calculated.With direct current control methods,compensation current is generated.The mathematical model of whole compensation process is established and current control algorithm,voltage control algorithm,on-off time of IGBT control algorithm is analyzed.Results show that D-STATCOM can complete reactive power compensation and harmonic suppression. |
