Effect Analysis of Static Gain of Excitation System and Generator Active Power on the Reactive Current Compensation
摘要
Abstract
The excitation static amplifying gain (K) and active power have great influences on the generator voltage droop characteristics. The effects of K on generator voltage droop characteristics without reactive current compensation are analyzed, and the effects of K on reactive current compensation are studied. At last, the influences of active power on the generator voltage droop characteristics are analyzed on a single machine infinite bus system. The results show that when K is smaller, the terminal voltage drops more along with reactive power increases, and the effects of reactive current compensation are reduced evidently, so the active power has great influences on the terminal voltage; when K is large enough , the influences of active power on terminal voltage will be very small. If only K satisfies the national standard demand, the influences of active power on terminal voltage can be ignored.关键词
