Layered exchange and control method for real-time monitoring system data by power dispatching

Abstract

The invention provides a layered exchange and control method for real-time monitoring system data by power dispatching. A CIM/XML (common information module)/(extensible markup language) interface, a CIM/E interface and other models of the electric power subsystems are processed and combined to establish a device model of the large power grid, therefore, perfect interaction of various application data including SCADA (supervisory control and data acquisition) real-time data, WAMS (wide area measurement system) data, EMS (enhanced message service) advanced application data and dynamic security analysis warning information can be realized, and power system control commands among the systems can be smoothly transmitted and executed. A data acquisition and exchange function can support multiple communication protocols, multi-application, multi-type and large amounts of data, satisfy the real-time requirements of all transmission environments, and provide comprehensive multi-scale real-time operation information of the power grid for other application analysis systems. A close integration mode is used to realize application integration and each subsystem and application can be monitored and managed, so a uniform access interface and a man-machine interface can be ensured to provide for each application system.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a layered exchange and control method for data in a power dispatching real-time monitoring system. Background technique [0002] At present, the master station of the power dispatching real-time monitoring system running on-line is in data communication with the real-time running sub-station system. After the system has been debugged, the data can be communicated normally and the acceptance is passed, considering the safety and stability of the power system operation, research and online control of various operation modes are not allowed. Existing discussion and research are all based on offline methods, which lack pertinence and operability, and have certain limitations. On the other hand, the existing SCADA system is connected to the RTU substation, and the refresh cycle is at the second level, while the WAMS subsystem is connected to the PMU substation, the refresh cycle is at th...
