Power distribution network operation online analysis and evaluation system

Abstract

The invention discloses a power distribution network operation online analysis and evaluation system. The power distribution network operation online analysis and evaluation system comprises an online collection unit, a comprehensive evaluation unit and a data application unit, wherein the online collection unit comprises an evaluation data preprocessing module and a plurality of data acquisition interfaces; a data processing result of the evaluation data preprocessing module is sent into the comprehensive evaluation unit; the comprehensive evaluation unit is combined with an evaluation system base and an evaluation rule provided by an evaluation rule base, and a comprehensive evaluation result is output to the data application unit after the calculation; and the data application unit comprises an evaluation reporting module and a comprehensive exhibition module and is used for outputting the comprehensive evaluation result of the operation of a power distribution network to the outside. With the adoption of the power distribution network operation online analysis and evaluation system, defects and deviation in operation and maintenance processes of the power distribution network can be found, and necessary technical measures are adopted to solve the problems in time, so that the operation and maintenance level of a power distribution automatic system is effectively improved.

Description

technical field [0001] The invention relates to an online analysis and evaluation system for distribution network operation, which belongs to the technical field of distribution automation. Background technique [0002] Distribution automation is an important means to improve the production and operation management level of distribution network and improve the reliability of power supply. In order to implement the requirements of the State Grid Corporation of China on improving the construction and application of distribution automation, domestic and foreign distribution automation system manufacturers have conducted long-term and in-depth research on the comprehensive evaluation technology of distribution networks, and achieved phased results. However, the medium-voltage distribution network is a key link of the entire power grid. It has the characteristics of complex structure and huge data volume. Requirements for safety and reliability, information sharing, and practica...

Problems solved by technology

The system is embedded in PMS (Production Management System) for secondary development. By integrating PMS equipment information, it realizes the assessment of the current situation of the provincial direct power distribution network. Analyze non-real-time data, and cannot comprehensively evaluate other distribution-related systems

Later, based on this system, the power company of the province developed a set of intelligent distribution network operation monitoring platform, collected statistical data from DMS (distribution automation system) in various places, and brought them together to the operation monitoring platform for comprehensive display. Unified supervision to a certain extent, but due to the large data granularity, strict data inspection and faulty device tracking cannot be achieved, and the supervision is slightly weaker
