Measurement and control device connected with double sets of process layer devices in intelligent substation and measurement and control method thereof

Abstract

The invention discloses a measurement and control device connected with double sets of process layer devices in an intelligent substation and an implementation method thereof. The measurement and control device comprises an intelligent power module, a master management CPU (central processing unit) module, a human-computer interaction module and two I / O (input / output) functional submodules. The master management CPU module collects, processes and then retransmits the data information acquired by the intelligent power module and the I / O functional submodules to a background monitoring and telecontrol device via an Ethernet, and the human-computer interaction module is controlled by human-computer interaction software to display and output the data information; meanwhile, the master management CPU module receives and retransmits control operation commands to the I / O functional submodules or the intelligent power module; and the master management CPU module is controlled by master management CPU software to process two sets of redundant data. By means of flexible software and hardware configuration, the invention can be adapted to the changing requirements of engineering applications, solves the problem on how to simultaneously connect the double configured process layer intelligent devices into an independently configured alternate measurement and control unit, and meets the requirement for the measurement and control device of the intelligent substation.

Description

technical field [0001] The invention relates to a measurement and control device of a power system, in particular to a method for realizing a single set of measurement and control device of an intelligent substation connected to two sets of process layer equipment. It belongs to the technical field of intelligent substation. Background technique [0002] With the continuous development of smart substation construction, the pilot projects range from 110kV, 220kV to 500kV, and the configuration requirements for secondary equipment of different voltage levels are not the same. The specification requires that the voltage level of 220kV and below should adopt the integrated configuration of protection, measurement and control. For 220kV and above It is advisable to adopt the principle of independent configuration of protection, measurement and control, and dual configuration of high-voltage level protection, which requires the dualization of intelligent terminals and merging unit...
