A training system and method for seamless switching of measurement and control devices from different manufacturers in substations

Abstract

The invention discloses a training system and a method for the seamless switching between measurement and control devices of different manufacturers in a transformer substation. The training system comprises a station control layer and a spacer layer, and is connected to a communication network through a data switch. The station control layer comprises an NS3000 simulated transformer substation comprehensive monitoring background machine. The NS3000 simulated transformer substation comprehensive monitoring background machine comprises a set of device one-key switching software tools. The spacer layer comprises a measurement and control screen cabinet. The measurement and control screen cabinet at least comprises an old measurement and control device and further comprises a novel measurement and control device, a terminal switching device, a simulation circuit breaker and a simulation test source, wherein the old measurement and control device and the novel measurement and control device are manufactured by different manufacturers. According to the invention, during the transforming and upgrading process of the transformer substation, the whole seamless switching process between measurement and control devices of different manufacturers can be simulated. The training process comprises the function test step before the switching of measurement and control devices, the software and hardware switching step and the functional verification step after the switching of measurement and control devices. The system and the method facilitate the systematic teaching and realize the full coverage of the professional knowledge.

Description

technical field [0001] The invention relates to a training system and method for seamless switching of measurement and control devices from different manufacturers of substations, and belongs to the technical field of comprehensive automation monitoring of substations. Background technique [0002] With the continuous development of intelligent electricity in our country, the application of substation integrated automation monitoring system in substations has become very popular. At present, the automatic monitoring system has become the most indispensable secondary application system in the substation construction. It plays an important role in ensuring the stable, safe and high-quality operation of substations, and is also an important judgment basis and maintenance tool for operation and maintenance personnel to analyze and deal with accidents in a timely manner. [0003] However, with the passage of time, some problems have also appeared in the integrated automation mea...

Problems solved by technology

[0003] However, with the passage of time, some problems have also appeared in the integrated automation measurement and control devices of substations, such as: the operation time is too long, the failure rate increases; the same type of equipment has been discontinued, and there is a lack of spare parts; the existing relevant technical indicators have become relatively backward , such as: the timing accuracy of the measurement and control devices that have been put into operation is poor, the SOE resolution is low, the sampling accuracy of the measurement and control devices that have been put into operation is low, the communication methods of the measurement and control devices that have been put into operation are complicated, and the measurement and control devices that have been put into operation do not support the IEC61850 protocol; The devices are all imported from ABB, Siemens, etc., and the technical support from the manufacturer cannot guarantee safety and good operation; the new measurement and control devices that have been put into operation and the new measurement and control devices used in the expansion interval cannot communicate normally, which has brought great impact to the stable operation of the substation. potential safety hazards, and it is also not conducive to the further development of substation integrated self-system

[0004] In order to solve the above problems, it is necessary to transform the measurement and control equipment of the original monitoring system, so as to get rid of the current situation of shortage of spare parts and weak technical support of imported equipment as soon as possible.
