| 摘 要： | 分析已有无功补偿控制器存在的问题,认为电力系统高次谐波的存在是影响电子式无功补偿控制器正常运行的关键,设计了高次谐波滤波器.由于滤波器存在相移,以往的相位识别方法存在盲区,对此提出了可适应任意接线方式的相位识别技术,并给出了补偿电容投切优化控制算法.

| Abstract: | The paper analyzed the existing problems of the idle compensation controller. The paper held that the higher harmonic wave existed in the electric power system was the key influence to the normal operation of the electric idle compensation controller. A higher harmonic wave filter was designed. Due to the phase displacement of the filter, the previous phase identification method has a blind area. So the paper provided a phase identification technology suitable to any wire connection type and provided the calculation method of input optimized control to compensate the capacitance. |
