汽轮发电机组进相能力评估及改善策略

Evaluation and Improvement Strategy of Turbine Generator′s Leading Phase Capacity

随着广东电网电压质量管理及无功电力管理要求不断提高,对发电企业的无功补偿提出更高的要求。对某火电700 MW机组相关运行数据进行分析,评估机组的进相运行深度及其限制因素并提出改善策略,最后通过进相试验验证机组的进相运行能力,确保进相运行试验和实际运行中机组的安全稳定性符合广东电网要求。

With the continuous improvement of voltage quality management and reactive power management requirements of Guangdong power grid,higher requirements are put forward for reactive power compensation of power generation enterprises.The related operation data of a 700 MW thermal power unit are analyzed,the phase depth of the unit and its limiting factors are evaluated,and the improvement strategies are put forward.Finally,the leading phase operation capacity of the unit is verified through the leading phase test to ensure that the safety and stability of the unit meets the requirements of Guangdong power network during the leading phase operation test and actual operation.
