摘要: |
根据宝钢电厂0号和3号发电机无功调差试验数据,计算两机调差特性,分析了发电机无功分配与机组容量不相配的问题,为此提出了对于并列运行的发电机在并列点调差系数应相等的要求,将两机AVR调差系数都设定为5%的对策,同时建议适当提高0号机电力系统稳定器PSS的增益。 |

Abstract: |
It is pointed out that the difference coefficients of generators running in synchronous status should be same.Based on the data of reactive power difference test for No.0 and No.3 generators of Baogang power plant,the difference characters of both generators have been calculated.The problem that the reactive power distribution between No.0 and No.3 generators of Baogang power plant does not accord with the respective unit capacity has been analyzed.It is suggested that the AVR (Automatic Voltage Regulator)difference coefficients of the both generaors should be modified to 5% and the PSS(Power System Stabilizer) gain of No.0 generator should be increased properly. |
