Embodiment Construction

[0032] The present invention will be further described below through specific embodiments.

[0033] refer to figure 1 , an intelligent second-level power restoration method oriented to regulation and control services, comprising the following steps:

[0034] 1) According to the grid steady-state data, monitoring alarm information, protection action information combined with Petri net to realize automatic identification of grid faults. The Petri net is pre-configured with an intelligent alarm rule library and intelligent fault judgment strategy. The intelligent alarm rule library has a keyword library: differential, high frequency, distance, zero sequence, bus difference, gas, overcurrent, current, gap, post-acceleration, longitudinal difference, failure, complex pressure, voltage, etc. Fault intelligent judgment strategies include voltage loss judgment, voltage loss range judgment, power transfer path search, power transmission self-inspection, etc.

Abstract

The invention discloses an intelligent second-level power restoration method and system for regulation and control services. The method comprises the steps: 1) realizing power grid fault automatic identification according to power grid steady-state data, monitoring alarm information and protection action information in combination with a Petri network; 2) realizing automatic screening and evaluation of a power restoration path according to the result of power grid fault automatic identification by combining traversal and search of a graph and a load flow calculation technology; 3) graphicallydisplaying a fault influence range and a power supply recovery path; and 4) automatically generating and executing a remote control sequence according to the power restoration path. Power grid fault full-flow automatic and intelligent processing can be realized, more accurate fault judgment, influence range and fault processing information can be provided for regulation and control personnel, andthe power failure time can be remarkably shortened through automatic execution of the power recovery control sequence so that the safe and stable operation level of the power grid is improved.

Description

technical field [0001] The invention relates to the field of electric power system automation, in particular to an intelligent second-level restoration method and system for regulation and control services. Background technique [0002] With the development of technology and the construction of smart grid, the dispatch control system will gradually develop towards the cloud architecture, and the dispatch control system will be automated and intelligent. However, at present, the business handling process for grid faults and recovery of the control system is still relatively traditional and isolated, with a low degree of automation and intelligence, and the entire process of fault handling has not yet formed an effective connection. How to build an automated and intelligent power grid fault handling system to better protect the safe and stable production of the power grid has become an urgent problem to be solved. Contents of the invention [0003] The main purpose of the p...
