A Stability Simulation Method of Power Network

Abstract

The invention provides a power network stability simulation method. The method comprises the steps that the status information, node connection information and current load information of a power network are acquired; the respective reliability value is calculated by using a plurality of different methods; the weighting parameters of a plurality of different methods are acquired respectively; weighted summation is carried out on a plurality of different methods; whether the reliability simulation result exceeds a first threshold value range is judged according to comparison of the summation result with a first threshold value; if the first threshold value range is exceeded, a warning signal is adopted to start a first-level pre-plan; if the first threshold value range is not exceeded, whether any one exceeds a second threshold value; if any one exceeds a second threshold value range, a reminding signal is adopted to start a second-level pre-plan; if any one does not exceed the second threshold value range, the information in the above steps is stored in a repository; and the above steps are repeated to carry out iterative loop. The method can accurately, fast and timely detect problems. The corresponding efficiency and the utilization of effective information can be improved. Problems can be rapidly solved. A serious power failure can be avoided, or danger caused thereby can be reduced.

Description

technical field [0001] The invention relates to the field of power network data signal processing, and more specifically, to a power network stability simulation method and device thereof. Background technique [0002] With the rapid development of my country's economy and society, the scale of the power network has expanded rapidly in recent years. While ensuring economic transformation and development, it has also brought great pressure to the management of the power network. Because the risk of blackout in the power network always exists, sometimes it will even cause network nodes to have domino problems due to the increase in load brought by the supply. Although the probability of this happening is not high, it is not a zero-probability event, so once it happens, It will cause great harm, which not only causes huge economic losses, but also brings damage to social management and operation. At the same time, this phenomenon brings challenges to the stable operation of the...

Problems solved by technology

However, in the existing technology, there is no unified and effective theoretical framework for the simulation and prediction, and the basic principles and purposes of various theories are not the same. The existing technology focuses on explaining the detailed process of each method without doing more analysis on the applicability of the algorithm , or only rely on historical data to speculate and determine without subjective initiative to make reasonable predictions

Or, some existing technologies only rely on the obtained result data to make a single judgment, and fail to effectively use the hidden danger information exposed by the important data in the process, resulting in the payment of necessary electric power, but the corresponding efficiency and the utilization of effective information. very limited
