Title  Electric parameter acquisition and remote control   System                                            

Abstract As national economy keeps growing and standard of citizen living raises a lot, people have a higher demand of power supply which requires the power system to be economic, convenient and stable, thus it’s of great significance to study the application and improvement of power distribution automation system.  Power distribution automation is an automation system which enables power enterprise to monitor, coordinate and operate power equipment in time. By collecting electrical parameters, motion control system can monitor and control device in operation. And it can collect data, control device, adjust parameter, alarm for emergency and etc. This design is based on I-7000 distributed module measure and control system, and use RS485 bussing technique to communicate, thus realizing the function of measuring, monitoring and controlling in a long distance. Also, a relay protection system is designed to protect the circuit. By modeling measuring system, this design enables people to know more of low-voltage power distribution system, as to realize the application of power distribution automation system.

Key words: distributed measurement and control, power collection, RS485, relay protection
