[New Energy Industry] Case Analysis of Low-Voltage Intelligent Hybrid Filtering Devices in the New Energy Industry
Time：
2019-08-27
A low-pressure intelligent hybrid filtering device TSVGGD is designed on-site for the large cracking furnace of Hunan Dingli Technology Co., Ltd. (mainly consisting of active filtering modules and intelligent filtering compensation modules produced by LiDAR Electric). This device aims to improve the power factor, filter out characteristic subharmonics, stabilize system voltage, enhance power quality, and ensure the safety of production electricity.
Customer name:Hunan Dingli Technology Co., Ltd.Company
Project background
Hunan Dingli Technology Co., Ltd. is a professional manufacturer of powder metallurgy special equipment, lithium-ion battery material production equipment, C and SiC ceramic fiber material equipment, solar polycrystalline silicon casting furnaces, vacuum heat treatment equipment, and other series.
The main products are applied in the National Key Laboratory of Powder Metallurgy at Central South University, the Key Laboratory of Aerospace Materials at the National University of Defense Technology, the Guangzhou Nonferrous Metals Research Institute, Porite Industrial Co., Ltd., etc., holding a significant market share domestically and exporting to the United States, Japan, Thailand, Taiwan, and other countries and regions.
Electricity summary (new energy)
Supporting the Tianjin large cracking furnace equipment produced by Hunan Dingli Technology Co., Ltd., applied in the Key Laboratory of Aerospace Materials, as this equipment has a large reactive power demand during normal operation, and generates5th and 7th harmonics, affecting the stable operation of other equipment and impacting product quality.
Design plan
Designing a set oflow-voltage intelligent hybrid filtering device on-site for the large cracking furnaceTSVGGD (mainly includes active filtering modules produced by Guanda ElectricActive filtering moduleandintelligent filtering compensation module) to improve power factor, filter out characteristic sub-harmonics, stabilize system voltage, improve power quality, and ensure safe production electricity.
low-voltage intelligent hybrid filtering device on-site for the large cracking furnaceEffect analysis
After the operation of the low-voltage intelligent hybrid filtering device (dynamic filtering compensation device) TSVGGD, the system power factor increased from about 0.39 to above 0.95, the average system operating current decreased from 1176A to 795A, and the 5th current harmonic distortion content decreased from 155A to 24A, solving the user's power quality issues and saving more than 10% on electricity costs.
Operating data
Before installation, the system power factor was about 0.39
After installation, the system power factor was above 0.95
Before installation, the absolute value of 5th current harmonic distortion was 155A
After installation, the absolute value of 5th current harmonic distortion was 24A
