Abstract

The invention relates to the technical field of power, and especially relates to an electric energy quality monitoring system. The system comprises an electric energy quality monitoring terminal, a monitoring center main station, and a work station. The monitoring center main station and the electric energy quality monitoring terminal are connected with an electric energy quality monitoring management application system through network lines. The system can be used for building the electric energy quality monitoring management application system which accords with a power grid system building standard and is opened in a unified manner, so as to build a power grid electric energy quality monitoring, estimation, hazard analysis and measure management system netweork. Through the analysis and enhancement of power grid electric energy quality supervision and management, the system can guarantee the safe and stable operation of a power grid. Through the analysis of monitoring data, the summarizing of causes and the proposing of corresponding rectification measures, the system carries out the comprehensive treatment of electric energy quality, improves the power supply quality, reduces the equipment faults and power failure time, reduces the energy consumption, and provides advices for the optimization of the power grid and fault analysis.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a power grid power quality monitoring system. Background technique [0002] In modern production, electricity as the main energy source, like any other tangible product, also has an important attribute, that is, quality. In many industrial enterprises, such as iron and steel enterprises, the high-power electrical equipment used produces a large number of high-order harmonics, peak pulses and other power pollution, which has seriously endangered the power quality. On the other hand, a large number of precision electronic equipment used , The computer control system puts forward stricter requirements on the power quality. This contradiction has become increasingly acute, and has attracted the attention of the majority of technical personnel. [0003] Therefore, power quality monitoring is the prerequisite for the power company to understand the performance of its power sy...
