摘　　要：南阳鸭河口电厂#2汽轮机为瑞士ABB生产的亚临界中间再热三缸两排汽冷凝反动式汽轮发电机组,因机组热耗率高,被列为应急备用机组。随着特高压输电和风电与光伏的大规模持续并网,电网的无功调压问题逐步突出,根据电网需求,改造为发电、调相两种模式灵活切换的运行方式。#2 steam-turbine generator of Nanyang Yahekou Power Plant was a subcritical steam-turbine generator made by ABB.It was classified as an emergency standby unit for its high heat consumption.With the development of UHV power transmission and large-scale grid-connected of wind and photovoltaic power generation,the problem of voltage regulation is becoming more and more serious.The steam-turbine generator was reformed to generation and phase modulation dual operation.
