Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, a method for assessing the risk of power grid load loss based on the PSASP model and the strategy of standby and self-commissioning includes the following steps:

[0024] S1. Extract the data card in the PSASP power flow calculation model:

[0025] At any time, extract node cards (bus cards, unit cards, etc.), branch cards (line cards, main transformer cards, etc.) and virtual branches that simulate the bus connection mode inside the plant from the PSASP power flow calculation model maintained by the operation mode department Among them, the bus card and unit card are uniquely identified by 8-byte names (consisting of region, station, and bus abbreviation) and voltage level, and the line cards and main transformer cards are identified by 13-byte names (the line cards start with , terminated station abbreviati...

Abstract

The invention provides a power grid load loss risk assessment method based on a PSASP model and an emergency power supply automatic throw-in strategy. The method includes the steps of extracting a node card, a branch card and a virtual branch card of a PSASP load flow calculation model, establishing a mapping relation between emergency power supply automatic throw-in device action logic and the PSASP load flow calculation model, establishing an emergency power supply automatic throw-in device strategy simulation model configuration table and conducting power grid power supply load loss risk simulation assessment. According to the method, the problem that power grid power supply load loss risk cannot be accurately assessed in power grid operation research and analysis work is solved, previous power grid fault simulation analysis modes are changed, a powerful technological support is provided for simulation analysis work of faults of a power grid N-1, a power grid N-2, important transmission sections and the like, and power grid potential safety hazard checking and controlling are analyzed more accurately and effectively.

Description

technical field [0001] The invention relates to the technical field of power system simulation calculation, in particular to a power grid load loss risk assessment method based on a PSASP model and a standby self-switching strategy. Background technique [0002] The main forms of backup self-switching devices are bridge backup switch, bus tie backup switch, section backup switch, incoming line backup switch, and transformer backup switch. Work or switch users to backup power. At present, it is an effective method to ensure the reliability of power supply to install self-switching devices in substations, so it has been widely used in power grids. The DTS simulation and power grid fault analysis modules of dispatching automation systems at all levels must fully consider the impact of backup and automatic switching on the power grid, otherwise the calculation results will be very different from the actual situation. [0003] After the promulgation of Order No. 599 of the Stat...
