Problems solved by technology

At present, the state of equipment such as units, lines, and transformers in the power grid model is only in operation and out of operation, and the state description is single, which cannot satisfy the accurate description of the state of the power grid.
The real-time state of the power grid cannot control the cause of equipment outage, and the availability of equipment cannot be determined in the future state; the power grid topology based on power flow calculation is not refined enough, and the availability of the calculated results is relatively poor
The operation of the power grid is becoming more and more complex, and the lean description of the operating conditions of the power grid equipment plays an important role in the formation of accurate basic data for power grid analysis. The existing analysis methods need to be improved urgently, and new solutions should be found

Abstract

The invention provides a power grid main equipment working condition analysis method and system. The method comprises the steps that S1, the actual operation condition and maintenance data of power grid main equipment are acquired; S2, according to the physical connection mode of the power grid main equipment in the topology, the actual operation condition of the power grid main equipment and themaintenance data, the operation conditions of the power grid main equipment in different time states are analyzed, wherein the different time states comprise at least one of the following states: a real-time state, a future state and a historical state. Compared with the traditional method for describing the running state of the equipment as available or unavailable, the method has the advantage that the running working conditions of the equipment in a future state, a real-time state and a historical state can be more accurately and visually described. The description can enrich the power flowcalculation selection based on the state of the power grid equipment, so that the power flow calculation is closer to the actual operation condition.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, in particular to a method and method for analyzing multi-state working conditions of main equipment of a power grid. Background technique [0002] With the advancement of power market reform, the security and enforceability of power grids in various regions have put forward new requirements for power grid security management. In the future, with the development of the power spot market, intra-provincial spot transactions will be superimposed on inter-provincial spot transactions, which will bring greater difficulty to power grid management. At present, the state of equipment such as units, lines, and transformers in the power grid model is only in operation and out of operation, and the state description is single, which cannot satisfy the accurate description of the state of the power grid. The real-time state of the power grid cannot control the cause of equipment outa...
