摘　　要：在发电厂热工控制系统中,实现工程师站和各操作员站之间时钟同步的功能至关重要,它影响诸如报警监视和记录、数据收集、向控制系统采集和发送数据等功能,影响控制时序的准确性,是整台机组安全经济运行的基础。以往使用时间同步在同步时存在某些问题,为了彻底解决这些问题,采用全球卫星定位系统(GPS,Global Positioning System)作为标准时钟(当GPS信号丢失时,以工程师站时钟为标准时钟),以C++为开发平台,自行开发了控制系统时钟同步软件。该软件实际运行至今,可以显著减少工作量,简化操作,效果令人满意。It＇s very important to achieve the clock synchronization between the engineering station and the operator stations in Visual C＋＋ of power plant. The synchronization relate with the monitoring and recording of alarm, and the collecting, gathering and sending of data. The accuracy of clock control is the basis of generating set running. To solve the current problems of using manual or GPS serial synchronization, we have developed the clock synchronization control system with the GPS clock as the standard clock, when the GPS signal is lost, we take the clock of tile engineering station as,using c＋＋ development platform.Practical application shows that the system can significantly reduce the workload and simplify the operation.
