PSD-BPA-based upper and lower power grid operation methods network model integration system

Abstract

Disclosed is a high-and-low-level grid operation mode network model integration system based on PSD-BPA. According to the system, a grid computing device foundation database is established, the corresponding relations between dispatching units and devices are maintained, and meanwhile, card information each dispatching unit can manage is determined according to the corresponding relations among dispatching units, devices and BPA cards; high-level dispatching units send modes to low-level dispatching units through parallel or serial strategies; when the low-level dispatching units maintain corresponding modes, modified contents are automatically compared with an original issuing mode to obtain differential contents; the low-level dispatching units complete corresponding modes and call the PSD-BPA to submit the differential contents to the high-level dispatching units through power flow calculation and stability calculation; the high-level dispatching units extract the differential contents submitted by the low-level dispatching units to automatically conduct combination on the modes submitted by the low-level dispatching units one by one, and automatically calls the calculation command of the PSD-BPA to conduct power flow calculation and stability calculation. According to the high-and-low-level grid operation mode network model integration system based on the PSD-BPA, users are liberated from a large amount of boring data processing, and working efficiency is improved greatly.

Description

technical field

[0001] The invention belongs to the technical field of electric power systems and automation thereof, and more precisely relates to the distribution and merging of power grids under multi-level regulation and control units. Analysis software package, which is collectively referred to as PSD-BPA in this paper), distributes power flow and stability methods of upper and lower power grids and integrates network models. Background technique

[0002] At present, my country is divided into five levels from top to bottom: national survey, network survey, provincial survey, local survey and county survey. With the rapid development of the national power system, the types and quantities of equipment managed by the power dispatching department are increasing, showing the characteristics of massive data and various models. In addition, with the clarification of dispatching authority, the hierarchical and partitioned management mode of power dispatching departments at al...

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] The operation mode of the power system is the core of the safe and stable operation of the power grid. In the integrated dispatching mode, the equipment of the power grid is regulated by multi-level dispatching units. From top to bottom, my country is divided into 5 levels: national dispatch, network dispatch, provincial dispatch, local dispatch, and county dispatch. Since the operation mode needs to consider factors such as the load demand of the whole province and even the whole network, the water inflow of hydropower stations, and future weather conditions, it is necessary to interact with the upper and lower dispatchers to ensure the reliability of the mode calculation. The current mode of interaction generally adopts the form of text interaction, which is inefficient and error-prone. The present invention proposes a method for issuing and merging the upper...
