摘　　要：国能神华九江发电有限责任公司(以下简称神华九江电厂)远动双主机运行模式为主备模式,通过1台主机进行数据接收与通信调度,另1台主机处于备用状态,当应用主机出现故障后,备机需要手动切换才能恢复运行。在切换过程中,当模拟量数据出现变化时,备机和调度主站连通后,模拟量数据的突变会影响调度对电网安全的管理。为实现并行式双主机运行与调度管理,需要对远动双主机运行模式进行改造。实验以神华九江电厂为测试对象,通过设计方案对该电厂的远动双主机模式进行改造,实现不同模式下2台主机自动转换连接,避免发生数据突变的问题。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.
