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...

Embodiment 2

[0047] On the basis of the above-mentioned embodiments, the power grid security analysis system provided in this embodiment further includes: a storage module 104, configured to collect the data collected by the collection module 101 and the results calculated by the calculation module 102 according to the data collected by the collection module 101 And the graphics generated by the graphics generation module 103 are stored so that the data can be called when needed.

[0048] Preferably, this embodiment can also be provided with a timing module 105, which is used to control the collection module 101 to collect data when the preset time arrives.

[0049] In addition, this embodiment is also provided with a unified interface for data transmission. Specifically, the system provides the GDA interface service in the standard IEC61970CIS interface, realizes the reading interface and update interface to serve each computing module, and the CIS interface supports multi-threaded servic...

Abstract

The invention provides a safety analyzing system of a power network. The safety analyzing system is used for collecting real-time data, parameter data and the like of the power network, and building the data into a visualized model according to an IEC61970 (international electrotechnical commission) standard, so a manual calculation work mode of the power network operation method is changed, the working efficiency is improved, and an auxiliary decision is provided for the arrangement of the power network operation method. The safety analyzing system has the advantages that the purposes of centralized management, graded use, and interaction and sharing of the calculation and analyzing results are realized, and a support platform is provided for the stable analyzing and calculation of cooperation trends for the upper-level and lower-level dispatching of the power network operation method.

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...
