Design And Development Of Smart Substation Testing Platform Of Connected Automatic Information

With the development of smart grid technology and the popularity of intelligent substation, the traditional power grid scheduling control type way already can not meet the demand. Intelligent substation automation system uses the mode of regulating the integration, namely "scheduling host + operations station". Intelligent substation compared with the traditional station, station device increases, the total amount of information increases, after the integration of control, alarm direct passing and composite signal is very large. Remote communication device as connection substation and dispatching the hub of communications, the main bearing the huge amount of information, only guarantee the correct TDD, timely and reliable transmission has information, in order to ensure the safe operation of power grid. Traditional method of remote debugging information mainly depends on the dispatcher to, with the station staff telephone communications station end staff give information according to the operator instructions manual device. Due to the traditional substation and dispatching the main interaction of less information, traditional basic debugging method can satisfy the practical application. And intelligent substation semaphore, commissioning method using traditional human time cost is larger, debugging inefficient.In this background, this paper puts forward a method of remote information automation debug, combined with the hardware device, data modeling, software module, debugging platform, designed to improve the efficiency and reliability of remote debugging information, the main work is as follows:1)Understanding of the development of smart grid and smart substation, substation automation system related equipment including: substation remote communication system, network packet analysis recording device, comparing the traditional substation and intelligent substation remote access way of communication.2)Construct platform for dispatching automation system architecture. Collect and record the message log analysis based on network device based on message function, establish communication with remote communication device to form a link closed-loop. The client as function realization of software platform and network message recording device to establish communication interaction.3) Based on IEC61850 hierarchical information model, analysis of network message recording device to abstract data modeling, and builds SCL configuration file.4) Design point signal ratio on the client side, and network based MMS message recording device, modified device data model by MMS service value control unit start/stop acquisition message, send much motivation to specify message information; Sending the MMS message receiver 104 packet forwarding far and motivation, for data processing.5) Intelligent substation dispatching automation information access debugging platform, and by simulating real substation environment, complete the test of remote communication link.
