| 摘要: |
| 针对实际无功规划和运行电压调控中关于高、低抗补偿效果的一些模糊经验认识,基于无功补偿调压估算模型,提出了高、低抗补偿调压的机理比较分析公式。在超高压系统中,主变高、低压侧并联高、低压电抗器对其主变高压母线电压的调节大小可分别通过无功补偿调压的一般估算模型及其拓展估算模型进行估算。分别位于华中电网送电电源中心和受端负荷中心的2个典型500kV变电站高、低抗补偿调压的实例仿真比较分析验证了高、低抗补偿调压估算公式的正确性和精确性。仿真结果表明:高、低抗补偿调压的大小主要由补偿点的短路阻抗参数决定;一般在低抗补偿调压不灵敏的地点高抗补偿调压也同样不灵敏,且在同一变电站相同容量高、低抗对主变高压母线电压的调节量之比基本保持稳定,并可通过提出的公式近似估算。 |

| Abstract: |
| To clarify some intangible experiential ideas in reactive power compensation planning and operating voltage control,the comparative analysis formulations of voltage regulation mechanism by high and low voltage shunt reactors are proposed based on the estimation model of reactive power compensation and voltage regulation. In EHV transmission system,the voltage range regulated by high or low voltage reactor connected respectively to the high and low voltage sides of main transformer can be estimated respectiv... |
