The Coordinated Technology Research Of Linkage Solutions Based On The LUA Dynamic Script For Substations Auxiliary System

Intelligent Auxiliary system is an important component of the intelligent substation. In order to optimize the operating environment in the substation, ensure safe and reliable operation of the substation,the auxiliary system shows the new features of many fields, involving a wide range of large amount of information. The discrete management based on Safety precautions, supplemented by equipment monitoring, can not meet the management of intelligent substation and the needs of development. It is urgent need for comprehensive monitoring of auxiliary equipment to improve the level of intensive management.In control center, which required by the "centralized operation" system bear the task of remote operation and centralized monitoring of equipment. achieving the remote centralized monitoring of auxiliary information, comprehensive analysis of information, The control center can keep abreast of the substation operating conditions and equipment operating status conveniently; The system can provide auxiliary check, shorten the time of processing accident, reduce the personnel workload of monitoring, operation and maintenance for the control center by the technical means of linkage auxiliary equipment for remote operation and alarm information, comprehensive analysis of the auxiliary information, Intelligent alarm, Multi-dimensional display and so on.With the advance of intensive management mode of Grid Corporation, It is urgent need for in-depth study on the overall structure of the auxiliary system, to explore and develop effective integrated solutions. We need to study the linkage program in the station of the auxiliary system to achieve a flexible and configurable solution, which in connection with the needs of optimize the environment in the substation to improve the efficiency of operation and maintenance.This topic will delve into the hardware and software architecture of the substation auxiliary system and the key technologies in the system. This topic propose the linkage solutions based on the LUA dynamic script and achieve a variety of linkage requirements with flexible scripting language, which in connection with the needs of the substation linkage in the intelligent assistance system and contrast the advantages and disadvantages of the different scripting language.This topic is a sub-topic of the environmental monitoring system in the substation.The study on the overall structure of the auxiliary system have great significance to improve the personnel efficiency of operation and maintenance、unattended substation management, stable operation and security guards.
