燃气-蒸汽联合循环分轴机组孤网运行分析

The Isolated Operating Analysis of the Gas-steam Combined Cycle Unit with Dual-rotor

燃气-蒸汽联合循环机组具有启动快速、辅助系统简单、调峰能力强等特点。FCB功能的实现能进一步提高电网的自愈能力,大幅提高本厂和电网的安全。文章从某次孤网运行事件中分析了三菱M701F4型燃气-蒸汽联合循环分轴机组孤网运行时出现的问题以及后期优化。

Gas-steam Combined Cycle Unit is characterized with high speed starting and stopping,strong capability of peak load modulation and few auxiliary systems.The realization of function of PCB(Past Cut Back)can further improve its capability of recovery and greatly reinforce the safety of the power plant and power grid.The article analyses the problems during isolated operation of Mitsubshi M7014 Gas-steam Combined Cycle Unit from one isolated isolation and its optimizing possibility?in the latter period.
