摘要
传统电压无功装置在调节时大都不考虑谐波因素的影响,而实际工程中谐波会带来很大危害。提出了一种具有谐波抑制功能的综合电压无功电能质量调节装置,并分析了系统谐波放大产生的原因及其抑制策略。此外,采用了多目标的电压无功谐波优化控制,同时考虑电压质量、无功、网损和谐波畸变率等多个优化目标,建立了多目标优化模型,实现对电压无功谐波的最优控制策略。仿真和实验证明了该装置及所得控制策略的有效性。
Traditional voltage quality control devices do not consider the harmonic factors in the regulation, but excessive harmonics may cause great damages in the actual project. An integrated VQC power quality regulating devices with harmonic suppression is proposed, the causes of harmonic amplification and suppression strategies are discussed. Furthermore, a multi- objective optimal control model is designed, considering power quality, reactive power, power losses and harmonics at the same time. Simulation and experimental results prove the effectiveness of the device and the control strategy.
