智能变电站测控装置目前没有备用，测控装置故障或异常时，相应电气间隔将失去测控功能。测控装置双重化方案曾进行过一些试点，实现技术已趋于成熟，但另增一套测控装置的成本过高阻碍了其推广应用。采用测控功能的集中式冷备用技术，能够以较低的成本解决测控装置无备用难题。文中详细描述了集中式冷备用所使用的虚拟测控装置的模型辨识技术、一致性验证技术，以及集中式备用解决方案。

In a smart substation without any reserve for measurement and control device,when measurement and control device becomes abnormal or is in maintenance status,relevant bay will lose the measuring and control function.Though a double control device in mutual standby state solution has had some trial operation and mature realization technology,the cost of an additional device will hamper popularization and application of this solution.It has been found that centralized cold standby technology used in measurement and control function can cut down the cost of solving the problem of measurement and control device without reserve.A detailed description is made of model identification technology of the virtual measuring and control device used by centralized reserve,consistency verification technology,and the centralized reserve solution scheme.
