| 中文摘要: |
| 针对扩大单元接线机组在AVC试验时存在无功争抢的现象,本文从AVC控制原理、发电机改变机端电压角度出发,分析了调差系数对无功负荷分配、电压灵敏度的影响.在Simulink环境下搭建了2*65MW扩大单元接线机组,研究调差系数对AVC控制效果的影响.结果表明,增大调差系数可以减缓机组之间的无功争抢,使母线电压调节到指令值,满足南网AVC技术规范要求. |

| In expanded unit connection units in the phenomenon of reactive power competition for AVC test, this article from the AVC control principle, the voltage of the generator to change machine Angle, analyzes the regulation coefficient of reactive load distribution, the influence of voltage sensitivity. Setting up in Simulink environment 2*65 MW expanded unit connection unit, studies the effect of regulation coefficient of AVC control. The results show that increasing regulation coefficient can slow the reactive power competition of unit between, make the bus voltage regulation to instruction value, satisfy the requirement of the south net AVC technical specification. |
