The Design of the General Concentrator

摘要

In the single-phase grounding fault location system for distribution network based on the phase method, the concentrator bears the main task of the centralized transmission data, and it is an important part of online fault location system. This paper designed a general concentrator. The concentrator cannot be only accurate upload fault information to the remote management center through GPRS module and wireless module, but also can give orders to the line terminal sensors. It also increased the GPS module, which can accurately obtain the local time, latitude and longitude location information. By the synergy of hardware and software, it implements the information interaction between concentrator and line terminal sensor, concentrator and remote management center. Through testing, the concentrator meets the requirements of real-time and reliability. The concentrator can be used for street light management system and electric power meter reading system, which has a broad application prospect.
