The invention provides a separation gatekeeper based method for filtering power system data. The separation gatekeeper based method includes the steps of extracting the power system data input to a separation gatekeeper by a power plant control system in real time; subjecting the power system data to data statistics and analysis to acquire a data filtering limiting value; filtering the power system data on the separation gatekeeper to acquire the effective power system data. Via extraction and statistical analysis for real-time data of the power plant control system, limiting value strategy for data filtering is made by combining relevance between current actual operation condition of the power system and data origins, the effective power system data can be acquired by filtering the power system data by the aid of the limiting value, and accordingly, an information system can run more stably, and abnormity of a displaying system is reduced.
Description
technical field [0001] The invention relates to data filtering technology, in particular to a power system data filtering method realized based on an isolation gatekeeper. Background technique [0002] The security isolation gatekeeper is a network security device that cuts off the link layer connection between the networks on the circuit by special hardware with various control functions, and can carry out safe and moderate application data exchange between the networks. [0003] For power secondary systems with high safety requirements, business processing systems and smart devices based on computer and network technology are used to monitor and control the power grid and the production and operation process of power plants. Including power data acquisition and monitoring system, energy management system, substation automation system, converter station computer monitoring system, power plant computer monitoring system, distribution automation system, microcomputer relay pr...
