Analysis and Application of Wireless Signal Optimization for Distribution Automation
摘要
Abstract
In order to solve the problem of poor reliability of wireless communication in distribution automation,this paper studies a strengthening scheme for wireless signal and develops a kind of portable wireless signal optimization device for dis-tribution automation based on extending RS-485 communication line. It firstly proposes an equivalent wireless signal strength model and develops a kind of device for measuring wireless signal for distribution automation,which can provide data sup-port for wireless optimization. Then it compares six kinds of conventional optimization schemes for wireless signal and dis-covers that the cost performance of way of extending RS-485 communication line is the highest which means this way is more suitable for requirements for wireless signal optimization in various scenarios. Finally,it develops a kind of portable wireless signal optimization device which can better solve the problem of weak wireless signal strength in operation maintenance and commissioning. Actual application indicates the optimized device can improve availability rate of the distribution terminal u-nit and is economic and reliable with simple principle as well as suitable for mainstream terminals.关键词
