中文摘要:

考虑到实现和控制的经济实用性,针对低压配电网中静止无功发生器(SVG)的运行控制问题,提出了一种改进式控制策略,该控制策略有恒无功、恒电压两种控制方式,能满足不同用户、不同地区的功率补偿需求。恒无功模式下的外环控制通过简单计算直接解耦q轴电流,避免了比例积分(PI)调节。通过在PSCAD/EMTDC中搭建的SVG系统仿真模型,对所提出的控制策略进行了仿真验证,并提供了大量的实验和仿真数据,仿真结果表明: 依据该控制策略设计的SVG系统响应速度快,直流电压稳定性好,动态补偿性能优,同时实现简单,因而具有一定的实用推广价值。

英文摘要:

Considering the economic practicality of implementation and control, operation control issues of SVG in low voltage distribution networks, an improved control strategy is proposed. To meet the power compensation needs of different users and parts, the constant reactive power and constant voltage control strategy is included. To avoid the PI regulation, in constant reactive mode, outer loop q axis current is decoupled through a simple calculation. Finally, a SVG model is developed in PSCAD/EMTDC to verify the proposed control strategy, both the real and simulative data are given. The simulation results prove that the designed SVG has certain practical value, with fast response, good DC voltage stability and well dynamic performance, is easy to implement.
