摘要
某些燃气轮发电机同期回路未配置闭锁继电器,存在非同期并网的安全隐患.为解决此问题,对某电厂燃气轮发电机同期回路进行研究,提出了在其同期回路中加装闭锁继电器的方案,进行闭锁继电器和中间继电器选型.现场试验证明,该方案能够提高燃气轮发电机同期并列的可靠性,达到了消除非同期并列安全隐患的目的,可为同类型燃气轮发电机同期回路加装闭锁继电器提供借鉴.
Abstract
Some gas turbine generators are not equipped with blocking relays in their synchronizing circuits,posing a potential safety risk of asynchronous parallelizing.To address this issue,the synchronizing circuit of gas turbine generator in a certain power plant is studied.A solution involving the installation of blocking relays in the synchronizing circuit of the gas turbine generator is proposed,and the selection of blocking relays and intermediate relays is conducted.The on-site tests demonstrate that this solu-tion can enhance the reliability of synchronous parallelizing of gas turbine generator,effectively eliminating the potential safety risk associated with asynchronous parallelizing,which can provide reference for the installation of blocking relays in similar syn-chronizing circuits of gas turbine generators.
