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 design and implementation method of a substation protocol conversion function. The ID mapping table of the virtual IED is configured under the IEC60870‑5‑103 protocol channel; a proxy IED is created in the IEC60870‑5‑103 protocol to realize the connection between the virtual IED and the virtual IED. The mapping relationship of IED; construct the proxy IED data transmission module in the IEC60870‑5‑103 protocol to realize the actual protocol data transmission with the monitoring system; design the timing distribution module of the IEC60870‑5‑103 protocol to integrate the communication between the monitoring system and the on-site IED The data is regularly distributed to the proxy IED for processing; data transmission during protocol conversion is realized. The invention avoids the configuration of the sending table or the information point table, reduces the occupation of data resources, can avoid the problem of data transmission error caused by the wrong configuration of the sending table, greatly improves the transmission efficiency, and satisfies the requirements of the monitoring system for different on-site IEDs in the substation. Data collection and monitoring realizes the unification and compatibility of communication protocols and communication methods, which is conducive to realizing 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...
