Integrated setting calculation system for operation characteristics of power transmission and distribution network

Abstract

The invention discloses an integrated setting calculation system for operation characteristics of a power transmission and distribution network. The system is based on servers of a national dispatching center, a national dispatching branch center, a provincial dispatching center, a regional dispatching center and a county dispatching center of a state grid company, and employs a distributed computing system developed on the basis of a Hadoop platform; the servers of the national dispatching center, the national dispatching branch center, the provincial dispatching center, the regional dispatching center and the county dispatching center of the state grid company are integrated into a computing platform through the Internet; the calculation capability of an existing server of a state grid company is fully excavated, and the power transmission and distribution network operation characteristic integrated setting distributed calculation is achieved. The system has the advantages of being small in investment, high in calculation efficiency and small in calculation error. The system adopts a distributed computing architecture, has good expansibility and high reliability, and realizes reliable and efficient power transmission and distribution network operation characteristic integrated setting computation; in addition, the system can increase the computing power through a method of adding a server to meet the further development requirements of the state grid; the system can be accessed to a server eliminated by the state grid company to realize secondary utilization of eliminatedassets.

[0002] With the rapid development of the domestic economy, the scale of the State Grid is becoming larger and more complex. It is difficult to clearly judge the partition pattern of setting calculation in the traditional sense. The upper and lower levels of the transmission and distribution network often affect each other, and the calculation becomes more In this case, the joint setting calculation of the large power grid based on the integrated application mode has gradually become the development direction of the relay protection setting calculation; however, the integrated setting calculation has the problems of large-scale transmission and distribution network model and low calculation efficiency. In order to solve this problem, relevant domestic research institutes have proposed various solutions, most of which focus on how to solve the boundary division and processing methods of the transmission and distribution network model, so as to realize the rational partition of the transmission and distribution network model and adopt synchronous parallel computing ; but these schemes are only an improvement to the original zoning calculation scheme, and various zoning calculation schemes will still bring calculation errors, so fundamentally they are not fully able to adapt to the rapid development of the national grid, and cannot adapt to the The State Grid has higher and higher requirements for safe operation; with the rapid development of the State Grid, the State Grid Corporation's national survey center, national survey sub-center, provincial survey center, ground survey center, and county survey center have deployed a large number of Servers are used to collect power grid information and monitor the safe operation of the power grid, but most of the time, the computing power of these servers is not fully utilized, resulting in a waste of computing power
