Provided is a power distribution network operation optimization system which comprises a real-time database, a power distribution optimization computation module, a real-time querying and setting module, a parameter and historical data interface module, a DA server and interface module, and a configuration module. The power distribution network operation optimization system, by means of an automation information processing platform, optimizes a breaker configuration scheme and a power distribution network operation mode, significantly increases the supply reliability of the power distribution network and decreases a line loss.
Description
technical field [0001] The invention relates to the technical field of distribution network operation, in particular to a system for optimizing the operation mode of the distribution network. Background technique [0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some ancillary facilities. It is a network that plays an important role in distributing electric energy in the power network. Distribution network is an important public infrastructure for national economic and social development. In recent years, my country's distribution network construction investment has continued to increase, and the development of distribution network has achieved remarkable results. However, the level of electricity consumption still lags behind the international advanced level, the development of urban and rural areas is unbalanced, and the quality of power supply needs to be improved...
