On-line large power grid recovery assistant decision-making system

Abstract

The invention relates to an on-line large power grid recovery assistant decision-making system. The system comprises two work modes, namely a real-time assistant mode and a research and analysis mode, a fracture surface operation analysis module, a calculation configuration module, a calculation function module and a calculation management module, wherein the fracture surface operation analysis module is used for fracture surface reading and fracture surface adjustment, the calculation configuration module is used for setting calculation parameters and selecting a black-start power supply and a started power supply, the calculation function module is used for system partitioning, load flow calculation, electromagnetic transient calculation, electromechanical transient calculation and path search and assessment, and the calculation management module is used for displaying system partitioning schemes, voltage waveforms, ranking of available paths and a black-start generating scheme. When the on-line large power grid recovery assistant decision-making system is used for developing an on-line electric power system recovery assistant decision-making supporting system, existing data resources in a dispatching center can be sufficiently utilized, the advantages of the method of pre-arranged scheme recovery and intelligent dispatching are combined, a model does not need to be rebuilt, the construction time and cost of the system are reduced, the real-time performance and the accuracy of suggestions to decision-making are improved, and a powerful support is provided for rapid and reliable recovery of a power grid after power outages.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an online large power grid restoration auxiliary decision system. Background technique [0002] Since the emergence of the power system, large-scale power outages have occurred from time to time. With the expansion of the scale of the power system, the frequency of occurrence is more frequent and the impact is more severe. On August 3, 1996, there was a nationwide blackout in Malaysia, on January 21, 2002, in the capital region of Brazil, on August 14, 2003, in the United States and Canada, in May 25, 2005 in Russia, in September 26, 2005 in Hainan The province-wide power outage, the South Korea power outage on September 15, 2011, and the Indian power outage on July 30, 2012, which affected the largest number of people in history, affected more than 670 million people. Large-scale power outages have brought huge economic losses to human beings, seriously affected people's lives, and...

Problems solved by technology

At the same time, as the scale of the power grid becomes larger, the scheduling operation information becomes more and more complex, the technical level and complexity of the power grid become higher and higher, and the difficulty of dispatching operation management becomes more and more difficult. The recovery of the power grid after a large-scale blackout Planning is becoming increasingly complex and difficult
