摘要
本文针对我国大型燃气轮发电机组保护配置现状,结合DL/T 1505—2016《大型燃气轮发电机组继电保护装置通用技术条件》,就燃气轮机的定子单相接地保护、定子绕组匝间保护、负载换相型变频器(LCI)直流接地保护、主变差动保护和变频算法的关键技术进行研究,以求有效保障燃气轮机的安全稳定运行,规范大型燃气轮发电机组保护配置并指导现场技术改造。
In this paper,according to the present situation of gen-transformer unit protection configuration on gas-turbine power plant in China,combined with DL/T 1505—2016 General Specifications for Large Capacity Gas-Turbine Generator Protection Equipment,key technologies such as stator grounding protection,stator inter-turn protection,load commutated inverter(LCI)DC grounding protection,and main transformer differential protection and frequency conversion algorithm of gas turbine generator are studied,thus guaranteeing the safe and steady operation of gas-turbine power plant,standardizing the configuration of protection standard and guiding the technical upgrade.
