Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Such as figure 1 Shown is a schematic diagram of the functional design and realization principle of the present invention. The present invention adds a protocol conversion function module between the original protocol conversion device and the monitoring system. When the intelligent electronic device IED (on-site IED) performs data interaction between the protocol conversion device and the monitoring system, the protocol conversion function added through the design The module converts different communication protocols into the standard IEC60870-5-103 protocol, which improves the automation management level. The specific functions and principles are described as follows:

[0026] 1) The protocol conversion device adopts various protocols for communicating with the on-site IED, and establishes communication with the on-site IED through a communication me...

Abstract

The invention relates to a method for designing and realizing a protocol conversion function of a substation. Configuring the ID mapping table of the virtual IED under the IEC60870-5-103 protocol channel; the proxy IED is created in the IEC60870-5-103 protocol to realize the mapping relationship with the virtual IED; the proxy IED data transmission module is constructed in the IEC60870-5-103 protocol to realize the actual protocol data transmission with the monitoring system; when the IEC60870-5-103 specification is designed, the module is distributed, and the communication data between the monitoring system and the on-site IED is periodically distributed to the proxy IED for processing; realize the data transmission in the protocol conversion process. The invention avoids the configuration of the sending table or the information point table, which reduces the occupancy of data resources, data transfer errors caused by misconfiguration of the send table can be avoided, it greatly improves the transmission efficiency, satisfies the data collection and monitoring of different field IEDs in the substation, realizes the unification and compatibility of communication protocol and communication mode, and is conducive to the interchangeability and interoperability of equipment in the substation automation system.

Description

technical field [0001] The invention belongs to the technical field of automatic management of power system substations, and in particular relates to a design and realization method of a protocol conversion function of a substation. Background technique [0002] Protocol conversion is an important part of the substation automation system, and plays a connecting role between the monitoring system of the entire substation automation system and the terminal equipment. The basic function of the substation protocol conversion equipment is to realize the data collection in the substation and the control operation of the IED through the establishment of communication with the intelligent electronic device (IED) in the substation; at the same time, it communicates with the monitoring system through the standard power industry communication protocol to complete Sending of data in the station and execution of operation commands of the monitoring system. Therefore, realizing the unifi...
