| 摘要: |
| 为避免谐波问题造成的电容器等设备损坏,提出了根据电容器和电抗器的滤波能力,把谐波抑制功能加入电压无功控制(VQC)装置。采用了按电容支路串联谐振频率点选择电抗器的方法;讨论了VQC动作原理、控制原则、控制策略。通过Matlab仿真分析,验证VQC装置在考虑谐波因素后的功能得到提高,在调节电压和无功功率的同时,有效地保护了电力设备。 |

| Abstract: |
| To avoid device damage caused by harmonic wave,a VQC device integrating harmonic suppression function is presented in terms of the filter capability of capacitor and reactor.The reactance value is selected according to the serial resonance frequency of capacitance branch.The action principle,control rule and control strategy of VQC are discussed.Simulation with Matlab verifies that,with the consideration of harmonic wave,the device has better performance in both regulating voltage and reactive power and protecting electric devices. |
