Abstract

An active dynamic compensation device and distribution transformer integrated monitoring method is disclosed. A monitoring terminal conducts on-site data acquisition analysis and control, and a monitoring background conducts running state monitoring and early warning. The monitoring background is formed by a communication server, a WEB/data storage server, a work station and a network isolation device, wherein the monitoring background communicates with the monitoring terminal through a GPRS communication means. The on-site type monitoring terminal monitors real-time electric quantity data and quasi-real time non-electric quantity data, wherein the real-time electric quantity data include reactive power, harmonic current, negative phase-sequence current, zero sequence current and three-phase voltage at the low-voltage outlet of a distribution transformer and the load side, and the monitored quasi-real time electric quantity data include shift, oil level, vibration, noise and oil temperature information of the distribution transformer, and the module state and module temperature information of the active dynamic compensation device. Integrated monitoring of the active dynamic compensation device and the distribution transformer can be completed, and the application effect of the active dynamic compensation device and the economic performance and reliability of the distribution transformer are improved.

Description

[0001] technical field [0002] The invention relates to an integrated monitoring method of an active dynamic compensation device and a power distribution transformer, belonging to the technical field of intelligent power distribution. Background technique [0003] With the development of economy and society, the majority of enterprises and residential users have higher and higher requirements for power quality, and the power quality control technology of distribution network has become a research hotspot. The power quality control of the traditional distribution network station area usually adopts the form of switching capacitors, which has problems such as poor dynamic response performance and easy generation of harmonic amplification. The application of active dynamic compensation devices to the low-voltage side of distribution stations to implement comprehensive control of power quality has become a technological development trend. Considering the high cost of the activ...
