Intelligent check anti-maloperation method based on real-time trend

Abstract

The invention relates to an intelligent check anti-maloperation method based on a real-time trend. By taking an electric power system model, a figure and real-time operation mode data as a basis, an intelligent anti-maloperation check program, before a dispatcher performs power network control, according to a current power network model and a running state, rapidly and automatically carries out a series of checks including a basis operation rule check, a dispatcher trend calculation check and a backup automatic switching rule check, wherein the basis operation rule check covers five universal protection rules and a topology check rule, and can carry out anti-maloperation check on equipment, an interval, a whole station and even a whole network; the dispatcher trend calculation check, through dynamic trend calculation, monitors the voltage and current values of a transformer, a bus and a line and gives a prompt about operation leading to off-limit; and the backup automatic switching rule check has an additional secondary equipment check function on the basis of a primary equipment check and provides comprehensive intelligent anti-error check information, such that the safety of scheduling work is improved, and emote maloperaiton can be effectively avoided.

Description

technical field [0001] The invention relates to an intelligent anti-misoperation method for preventing mis-scheduling and misoperation of a power system, in particular to an intelligent checking and anti-misoperation method based on real-time power flow. Background technique [0002] With the rapid advancement of the construction of the large-scale operation system, the responsibilities of the traditional dispatching center have also changed. In addition to the original dispatching responsibilities, they also shoulder the responsibilities of the monitoring center and become a real control center; the scale of the power grid managed by the control center is unprecedentedly large. , The complexity of the network is getting higher and higher, which puts forward higher requirements for the monitoring personnel. In such a complex power grid environment, a slight negligence may cause misoperation accidents such as mistakenly pulling the switch. [0003] Most of the current anti-er...

Problems solved by technology

[0003] Most of the current anti-error systems are based on the five-prevention system of substations, which can basically avoid misoperations based on intervals, but lack of error prevention based on the entire network. When the control personnel perform remote operations on the power grid, they are basically based on personal experience. Lack of a reliable error prevention logic
