A Discharge Test Detector Of Reactive Power Compensator

With the rapid development of market conomy, demand for electricity is increasing, dependence becomes stronger, low voltage electrical apparatus plays an important role in the bear power transmission and distribution, power equipment protection and control tasks. Low voltage reactive power compensation device is an important equipment of provide the necessary wattless power to improve power factor, reduce the energy consumption distribution system line, improve voltage quality. There is great significance to realize the economical society.Continued research and development of low voltage complete new product reactive power compensation device,requires a more advanced testing and analysis equipment to adapt to the development of it, meet the performance requirements of all aspects of testing, for the discharge test, require detection device can achieve instantaneous and real-time waveform data acquisition function, the automatic analysis with parameter test calculations, test results can be automatically generated report, and the testing equipment has the advantages of small volume, easy to move, so as to greatly improve the capacitor discharge test site detection efficiency;and the detection device of traditional have been unable to meet the requirements, therefore, the development of new detection equipment is very necessary. In order to solve the above problems, the voltage sensor, data acquisition card, PC, virtual instrument and formed a set of portable discharge without reactive power compensation device tester, using LabVIEW to develop the software realization of low voltage reactive power compensation device for capacitor discharge test of electrical parameters for automatic acquisition, processing, analysis and other functions,test field test a software program, combined with the use of the hardware part, forming a complete set of testing equipment, and the testing equipment and self calibration and measurement uncertainty analysis. At the same time, and experience the experience in practice based, without prejudice to national standards, further optimize the test process, make it more operational.This paper discusses the following aspects:Development and performance testing of low voltage reactive power compensation device;Design and implementation of capacitor discharge test instrument;Debugging, the testing uncertainty analysis and the practical application of.Experimental results show that, the design of portable capacitor discharge test instrument in meeting the national standard requirement for capacitor discharge test, discharge test performance can quickly complete low voltage reactive power compensation device, improve work efficiency, and greatly reduces the burden of testers, achieved good results. Use of LabVIEW software interface is friendly and easy to read, high precision, good stability, has good application value and development prospect.
