一种分布式无功与谐波补偿系统及其控制方法
摘要：
本发明涉及一种分布式无功与谐波补偿系统及其控制方法，属于无功补偿技术领域。为了解决目前已有补偿装置不能快速连续地完全补偿负载谐波与无功功率、补偿容量浪费且系统造价高昂的不足，提供一种低成本、大容量谐波与无功补偿能力以及快速连续的分布式无功与谐波补偿系统及其控制方法。一种分布式无功与谐波补偿系统，包括若干补偿单元、通讯模块和主站，各补偿单元和主站之间通过通讯模块进行通讯，所述补偿单元主要用于计算得到负载所需补偿的谐波和无功、自动补偿谐波和无功，所述主站实时控制不同节点的补偿单元投切。
摘要（英）：

The invention relates to a distributed reactive power and harmonic compensation system and a control method thereof, and belongs to the technical field of reactive power compensation. In order to solve the problem that a traditional compensation device cannot compensate the load harmonic and reactive power rapidly, continuously and completely, causes a waste of compensation capacity, and is high in system cost, a rapid continuous distributed reactive power and harmonic compensation system having a low-cost and large-capacity harmonic and reactive power compensation capability and a control method thereof are provided. The distributed reactive power and harmonic compensation system comprises a plurality of compensation units, a communication module and a main station, wherein each compensation unit and the main station communicate with each other through the communication module, the compensation units are mainly used for calculating the harmonic and reactive power required to be compensated for the load, and automatically compensating the harmonic and reactive power, and main station controls the compensation unit switching of different nodes in real time.
