Digital Dynamic Reactive Power Compensation Device

Overview

In view of the current situation, Lafaelt developed the whole life cycle monitoring system of reactive power compensation device. Through the self-developed smart capacitor monitoring module, real-time collection of capacitor switching current and real-time temperature information, monitoring the remaining capacity and switching status of each capacitor bank. Built-in advanced edge computing model to calculate the attenuation degree and service life of capacitor bank, to achieve the whole life cycle management of reactive power compensation device. The system can monitor the real-time output capacity of the whole cabinet, the cumulative running time of capacitor bank, real-time temperature and other information, when the capacitor current and temperature are abnormal, the system will alarm in real time, to avoid the occurrence of major electrical safety accidents such as explosion and fire, and truly realize preventive maintenance.

System Structure

The traditional reactive power compensation device is equipped with a smart capacitor monitoring module and a health status display smart screen to form a full life cycle monitoring system for reactive power compensation. Through the intelligent communication server, the collected data and fault alarms are transmitted to the cloud platform in real time, and users can view the real-time status and fault alarm information at any time, helping users realize intelligent unattended operation and maintenance management.

Application

LRTS-D device is mainly used for nonlinear loads such as large-scale welding equipment, driving cranes, and frequency conversion devices. It needs to obtain a large amount of reactive power from the grid in real time. The reactive power demand of new energy vehicles, integrated circuits and other industries changes rapidly, causing severe flicker and needs fast reactive power compensation.

Technical parameter

Typical Configuration

Digital dynamic reactive power compensation device grouping scheme

Rated voltage 400V/50Hz, SCR switching, 7% filter reactor in series, with phase split compensation, typical combination scheme

Note: When the reactive power compensation cabinet is mixed compensation, in order to ensure heat dissipation, it is recommended to divide it into main and auxiliary cabinets if the capacity of a single cabinet exceeds 480kvar.

Series 14% filter reactor with phase split compensation, model LRTS525-300/10-14-D, LRTS525-480/12-14-D, etc.
