An On-Line Large Power Grid Restoration Assistant Decision-Making Method

Abstract

The invention relates to the field of power systems, in particular to an online assistant decision making method for large power grid restoration. Corresponding steps of the online assistant decision making method are carried out in different selected working modes, and the working modes include a real-time assistant mode and a research and analysis mode. The online assistant decision making method has the advantages that the merit that dispatchers and equipment operators of a power plant and a transformer substation are familiar with the traditional plan type system restoration scheme when the traditional plan type system restoration scheme is adopted is kept in the real-time assistant mode, the work intensity of plan formulation personnel is relieved, the assistant decision making speediness, accuracy and reliability for power system restoration are embodied, and shortcomings that an actual condition of a power grid which is developed quickly is inconsistent with a designed condition of a plan, restoration paths involved in the plan are infeasible and the like are overcome specifically; almost all computation types which are possibly involved in formulating a common power grid black-start scheme are integrated in the research and analysis mode, typical power grid partition computation for large power grid restoration is added into the research and analysis mode, a scheme draft generating function can be realized, and the expenditure of time spent on integrating different result files is greatly saved.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an auxiliary decision-making method for online large power grid restoration. 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...

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
