Research and Application of Installing Blocking Relays in Synchronizing Circuits of Gas Turbine Generators
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.
