The system and method that power system N-2 simulation analysis process automatization realizes
Technical field
The present invention relates to the system and method that a kind of power system N-2 simulation analysis process automatization realizes。
Background technology
The safety of power system is the important indicator weighing operation of power networks, especially in recent years, frequently there is power outage in domestic and international electrical network, the large area blackout that successive failure causes, massive losses is brought to social production, life, although making work about electric power person progressively it is realized that the N-1 criterion of power grid security verification in the past is in most cases ensureing the safe operation of electrical network, but there is a few cases that serious follow-up major break down likely can occur。The particularly Large scale construction of the extra-high voltage of modern power network, the introducing of direct current transportation and wind energy turbine set, photovoltaic DC field, power system is more in the urgent need to fundamentally explaining and prevent that the electric network reliability that element or element group fragile attribute in the entire system cause lacks or even large-area power-cuts, thus electrical network must be carried out more harsh verification according to N-2 criterion by the safety and stability of electrical network, improve further the safety of network, prevent the situation of those " few occur but consequence is extremely serious "。
The subject matter faced in the process of current N-2 simulation analysis is:
(1) along with the scale of electrical network progressively expands, method of operation complexity is various, it is contemplated that accident set quantity is more and more huger, failure mode is various, and conventional analysis mode can only travel through various fault, takes time and effort, make to obtain the time lengthening analyzing result, strengthen the formulation time of power system operating mode。
(2) if only analysis part fault, then highly dependent upon the experience of operations staff。When manual operation experience is enriched not, it is likely that miss out some important accident element groups, the long-time band hidden danger of electrical network is caused to run, thus the safety of operation of power networks is constituted a threat to。
(3) after the change that electric network composition has carried out somewhat, it is necessary to the personnel that rearrange test one by one, substantially carried out many repetitive works, wasted human resources and easily make mistakes。
(4) N-1 only achieving sequencing at present analyzes, and N-2 analyzes but without forming efficient and quick scheme, it is difficult to ensure electrical network is realized omnibearing emulation。
Summary of the invention
The purpose of the present invention is contemplated to solve the problems referred to above, the system and method that a kind of power system N-2 simulation analysis process automatization realizes is provided, it has automatization and realizes copying, automatically multiple different operation method, N-1 can be analyzed and the analysis automated emulation of N-2, without artificial intervention, in addition, also there is self-learning function, operation result includes knowledge base system in, automatically it is calculated one by one analyzing by target area electrical network and the circuit specified, finally realizes the comprehensive exhaustively high-speed simulation of electrical network。
To achieve these goals, the present invention adopts the following technical scheme that
The system that a kind of power system N-2 simulation analysis process automatization realizes, including:
