摘要:

在特高压受电电网中,一次调频的作用愈加重要。大型燃煤机组担负着主要的一次调频作用,还有较多机组没有达到理想的性能指标,性能试验又较难发现问题。通过对考核机组的分析,提出了禁止与调频功率反向动作逻辑,提高调频能力的修正滑压曲线、修正前馈系数两类优化方案,供不同性能的机组选用。

Abstract:

In ultrahigh voltage power gird receiverside, primary frequency modulation became more and more important. Large scale coalfire power is responsible for primary modulation, but many units cannot achieve expected performance, and problems barely can be detected by performance tests. By analyzing tested units, prohibition and frequency modulation counter action logic was indicated. Corrected sliding pressure curve, which increases frequency modulating ability, and corrected feedforward coefficient was provided. This could be referred by different kind of unit.
