汽轮发电机改调相机关键技术

Key Technology of Transforming Turbine Generator into Phase Modifier

在“碳达峰、碳中和”的背景下,以风力和光伏为主体的新能源将逐步替代火电机组成为电网中的主力电源,电力系统对动态无功以及惯量的需求也逐步增加,将原有汽轮发电机改造为调相机,可以为系统提供大容量的动、静态无功功率支撑以及惯量支撑,同时有效利用火电关停后闲置的土地、厂房和设备。介绍了汽轮发电机改调相机对电力系统的作用以及改造的关键技术。

Under the background of“carbon peak and carbon neutrality”,the new energy dominated by wind and solar energies will gradually replace the thermal power units as the main power supply in the power grid,and the power system's demand for dynamic reactive power and inertia will gradually increase.Transforming original turbine generator into phase modifier can provide large-capacity dynamic and static reactive power supports and inertia support for the system,and at the same time can effectively use the idle land,plant and equipment after the shutdown of thermal power.This paper introduces the function of transforming turbine generator into phase modifier for the power system and the key transforming technology.
