摘要
介绍了丹江口电厂4号机组一次调频试验方法,测试了4号机调速器静态特性和一次调频动态响应特性,获取了一次调频相关技术数据,确定了4号机组一次调频功能的合理实现方式,并能保证可靠投入一次调频功能,达到了提高湖北电网的电能质量及频率控制水平的目的。
A method of primary frequency modulation test of unit No.4 is introduced,and the static characteristics of unit No.4 governor and the dynamic response characteristics of primary frequency modulation are tested.It gives the related data of primary frequency modulation and provides a rational way to bring about primary frequency modulation function of unit No.4.As a result,power quality of Hubei power grid and frequency control is improved.
