采用GPS/北斗双星同步采集技术的分布式无线高压绝缘带电测试的研究
A Study of Implementing GPS/BD PPS Pulse to Synchronize Sampling in a Disturbed Wireless System for Insulation Live Testing
摘要
Abstract
With the development of smart grid and CBM,it's important to get the insulation status of capacitive devices and MOA.The on-line testing and live testing are still insufficient in precision and equipment's reliability,so they aren't used widely by power companies.In this article,a portable live testing system which based on high-precision synchronize sampling with GPS/BD and wireless is studied to improve the precision and convenience of test.The systems theory is introduced,the technologies which apply hardware of GPS/BD-s PPS to start sampling of Σ-△ type AD,and coordinate with timing under flow control of software,and improve iteration-orthogonal algorithm,reduces the error of relative dielectric loss test,improves the repeatability and stability of data.The algorithm and synchronize performance are studied with comparison.The system's performance is tested.The result shows that this system can measure relative dielectric loss with very high precision which-s error less than 0.05％.This system has been used successfully in a substation's capacitive devices and MOA test,and it improves the test efficiency and cost performance greatly.关键词
