Remote testing data interface conversion device

Abstract

The invention discloses a remote testing data interface conversion device, which can transmit an analog quantity and a switching quantity outputted by a real-time simulation result of an RTDS simulation system in a laboratory to a stability control device currently operating in the field, can receive an actual action result of the field stability control device and feed the actual action result back to the RTDS simulation system, and realizes the bidirectional information interaction and wide-area closed-loop test of a test system and the stability control device currently operating in the field. The remote testing data interface conversion device is composed of a data processing master control unit, data acquisition interface units and a remote communication interface unit, wherein the data processing master control unit realizes organization and conversion of data, can adapt to data simulation of different stability control systems through parameter configuration, and has the advantages of good extensibility and flexibility; the data acquisition interface units can be additionally added or reduced flexibly according to the size of the test system; and the remote communication interface unit realizes communication between the data processing master control unit and a remote operating stability control device, and completes the information interaction with a remote plant station.

Description

technical field [0001] The invention relates to the field of power automation technology control, in particular to a data interface conversion device for remote testing. Background technique [0002] With the rapid development of UHV AC and DC power grids, the contradiction of "strong direct current and weak AC" in the power grid during the transition period is prominent, the proportion of new energy is further increased, and the stable operation of the power grid is facing greater risks. Power grid security and stability control system, building a comprehensive defense system for large power grids. The power system security and stability control system has a large scale, a large number of devices, and complex and changeable control strategies. Dynamic simulation tests must be carried out through the RTDS test system to ensure the operation of the security and stability control system. reliability. The traditional dynamic testing method for safety and stability control syst...

Problems solved by technology

The traditional dynamic testing method for safety and stability control systems is to build a test system basically the same as the actual system in the simulation laboratory, and conduct RTDS simulation tests intensively. This method requires a lot of wiring and configuration work in the simulation laboratory, and consumes a lot of work. manpower and material resources, and the test system is built according to the system structure, which does not have reusability, and the efficiency of the simulation test is low; on the other hand, the test system is limited to the test site and the number of test equipment, and cannot completely simulate the safety and stability control of the actual operation system, only a part of the system can be dynamically simulated, and sometimes the device software running on site must be adjusted to meet the requirements of the test, and the reliability of the simulation results is relatively low
