The remote control dual main-machine operation mode of Guoneng Shenhua Jiujiang Power Genera-tion Co.,Ltd.(hereinafter referred to as"Shenhua Jiujiang Power Plant")is the operation-standby mode,in which one machine receives data and completes communication dispatching,while the other is in standby mode,so that when the operating main machine fails,it is necessary to manually switch to the standby one to resume operation.In the switching process,when the analog data changes,after the standby machine is connected to the dispatching master,the sudden change of analog data will affect the dispatching manage-ment of grid security.For successful parallel dual main-machine operation and dispatching management,the remote control dual main-machine operation mode should be modified.In the test with Shenhua Jiujiang Pow-er Plant as the test object,the remote control dual main-machine mode of this power plant is modified ac-cording to the design scheme,aiming to ensure that the two main machines in different modes can be auto-matically switched and connected without sudden change of data.
