Research on Distributed Automatic Test System for Secondary Loop of Substation that Based on Wireless Communication

摘要

Conventional substation secondary loop connection is complex. There are the actual do not conform to the design drawing, testing and eliminating defects difficult and other issues. This article through to the substation secondary loop model, using wireless communication technology and the signal modulation and analysis technology to design a substation secondary loop distributed automatic test system, and expounds the system architecture of the system in detail, software framework, realization principle. Combined with a 220 kV substation line interval, such as the actual case of engineering application verified the effectiveness of the testing system, improve the testing efficiency and accuracy of the substation secondary loop. This test system for substation secondary system safe and stable operation has great significance.
