Abstract

The invention relates to an assistance determination system of a distribution network programming proposal in a electricity technical field, which includes a data input and output module, a power-supply reliability index generation module, a power-supply capacity index generation module, a power-supply quality index generation module, a short-circuit electric-current level index generation module, a projected economy index generation module, an integrated index generation module, a module for analyzing preconceived accident and displaying an analysis report on the preconceived accident consequence and an inquiry module for an calculation result on the assessment index of the distribution network. The data input and output module is used for inputting the data of the distribution network proposal into each index generation module, and outputting the assessment index calculated by each index generation module. Each index is calculated by each index generation module through calling a topology analysis and a power flow calculation, and the analysis reporting module and the inquiry module carry out an analysis and a report to each module respectively. The invention finds out existing problems and weak steps of the projected proposal quickly and accurately, and provides scientific basis for a revise and an execution of the projected proposal.

Description

Technical field [0001] The invention relates to a system in the field of electric power technology, in particular to an auxiliary decision-making system for a distribution network planning scheme. Background technique [0002] Grid planning is an important part of power system planning. Its task is to determine power supply planning and the best grid structure based on load growth to meet the requirements of safe, economic and reliable power transmission. The distribution network is located at the end of the power system and is directly connected to users. It is an important link in the power system to connect power sources and users. A safe and reliable distribution network is an important material basis for ensuring the stable and sustainable development of the national economy and people's living standards, and a scientific and reasonable distribution network planning is an important prerequisite for ensuring the safe, economic and reliable operation of the power grid. Distrib...
