An Analysis System for Power Network Security

Abstract

The invention provides a power grid security analysis system, which collects real-time power grid data, power grid parameter data, etc., and constructs the above data into a visual model according to the regulations of IEC61970, changes the power grid operation mode and manually calculates the work mode, improves work efficiency, and contributes to the power grid Operating mode arrangements provide support for decision-making. The system can realize centralized management, graded use, interactive sharing of calculation and analysis results, and provide a support platform for coordinated power flow stability analysis and calculation for power grid operation mode upper and lower dispatching.

Description

technical field

[0001] The invention relates to the field of power system data management, and more specifically relates to a power grid security analysis system. Background technique

[0002] With the rapid development of the power grid, the scale of the power grid is increasing day by day and the complexity of the power grid structure is increasing. The increasingly large models and rapidly changing data have brought great impact to the traditional power grid analysis. The superposition of various new technologies , the concept of power grid analysis is undergoing transmutation, specifically manifested in: the power grid analysis method develops from "deterministic analysis" to "probabilistic analysis", from "adequacy assessment" to "safety assessment", from "offline analysis" to " Online analysis", from "qualitative estimation" to "quantitative calculation". People have higher and higher requirements for the reliability of the safe power supply of power distribution syst...

Embodiment 1

[0026] In the prior art, the grid power flow calculation programs used in China are diversified, and the common ones include comprehensive programs, BPA, PSASP, and PSSE. Among them, each calculation software has a proprietary data file format, and an independent grid model needs to be maintained. Among them, the power grid model can be divided into four states: historical state, current state, future state and virtual state, in which the historical state is a past model, the current state is the current power grid operation model, and the future state is the increase that has been approved but not invested. The virtual state is the power grid model that is used to add some research. Among them, the historical state and the present state are mainly managed in the EMS system. Although some existing EMS systems have proposed the management of the future state and the virtual state, the research work done is still very limited, and because of the future state The difference betwe...
