Planning system for comprehensive optimization of regional power distribution network

Abstract

The invention provides a planning system for comprehensive optimization of a regional power distribution network. The planning system comprises a regional basic system data inputting and preprocessing module, an expert knowledge and equipment parameter information inputting and preprocessing module, a planning module of a substation of the regional power distribution network, an optimal section / interconnection switch configuring module, a wattless-voltage planning module of the regional power distribution network and a planning result outputting module. According to the planning system disclosed by the invention, through the adoption of the technical scheme, under the situation that the investment optimization is ensured, the capacity-load ratio of the substation of the regional power distribution network is increased within a certain range, the load rate of a circuit is decreased, the flexibility of regulating the operation manner is ensured, the safe operation and the dispatching management are facilitated, the reliability of the configuration of a section switch is ensured, and the economy of the configuration is also sufficiently considered; the wattless vacancy of the regional power distribution network is reduced, the voltage quality of the power distribution network is improved, and the economy and the high efficiency of the operation of a power grid are ensured.

Description

technical field [0001] The invention relates to the technical field of distribution networks, in particular to a comprehensive optimization planning system for regional distribution networks. Background technique [0002] The regional power distribution system is the main component of the power grid and the main load center of the power system. It has the characteristics of high load density, rapid load growth and high reliability of power consumption. Whether the power supply quality of the regional power grid is high-quality or not is an important factor affecting the rapid development of the regional economy, the steady and rapid progress of various constructions, and the guarantee of the material and cultural life of the residents in the region. The regional power distribution system mainly has the problems of low capacity-load ratio, high line load rate, large reactive power shortage and unreasonable network structure in distribution network substations, which makes the...

AI Technical Summary

Problems solved by technology

[0003] The current regional distribution network planning system has a single function, has strict requirements on the input data, does not have preprocessing and integration functions, cannot realize intelligent planning, and cannot optimize planning in an all-round and comprehensive way. In addition, due to its own complexity , requires high professional knowledge of the operator, and the interface is not friendly enough, etc.
