大型发电机组调差单元调差系数整定计算与试验方法

A Calculation and Test Method of Reactive Current Droop Compensation for Large Generators

大型发电机组调差单元提供的无功调差可以补偿升压变压器电抗,提高电力系统稳定性。发电机无功调差功能是励磁调节发电机无功出力的重要参数,尤其是对扩大单元接线的多台发电机运行,尤为重要。依据相关电力行业标准,提出了发电机组在各种并列运行方式下调差系数的整定原则和实用试验方法。

For improving power system stability, large generator reaeitve current droop compensation unit provides reactive power, which can compensate the reactor of transformer. Generator reactive current droop compensation is an important parameters of generator reactive power, especially for the expansion unit connection generators. According to the indnstry standards of the power system, this article provides a calculation and test method of reactive current droop compensation for large generators.
