Power distribution network load rapid transfer auxiliary decision-making system based on PI database

Abstract

The invention discloses a power distribution network load rapid transfer auxiliary decision-making system based on a PI database, and aims to overcome the problems that the data query process is complicated, the number of query systems is large, the number of repeated query systems is large, and the compilation efficiency of an operation mode is seriously influenced when a load transfer scheme is compiled in the prior art. The system comprises a PI database and a PB interface connected with the PI database. According to the system, a PI real-time database is utilized, a 10kV line contact mode and line and main transformer limit condition table is established, a real-time data display and historical trend chart query function in the PI database is utilized, various factors required by load transfer are integrated, a function of querying a superimposed load historical trend chart of a related contact line is provided, and by using the system, the time for formulating a scheme in a scheduling service can be greatly shortened, the working efficiency is improved, and safe and stable operation of a power distribution network is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to an auxiliary decision-making system for fast transfer of distribution network loads based on a PI database. Background technique [0002] In the power system, the accurate and efficient preparation of the distribution network operation mode is the basis for the safe and stable operation of the power grid. At present, the distribution network connection line is becoming more and more complex, which puts forward higher requirements for the rapidity of load transfer when the dispatching department fails in the distribution network or the upper-level power grid. However, as far as the current actual situation is concerned, the data query process is complicated when the load transfer plan is compiled, there are many systems to be queried, and the number of repeated system queries is large, which seriously affects the compilation efficiency of the operation mode. At pre...
