Method for testing new system through simulation four-remote signal generator

Abstract

The invention relates to a method for testing a new system through a simulation four-remote signal generator. The method refers to a four-remote signal simulation system. The four-remote signal simulation system comprises a remote signaling verification module, a remote measuring verification module and a remote control verification module. The four-remote signal simulation system simulates a PC into the situation that a substation communicates with an automatic system, change remote signaling parts and remote measuring parts are generated in batch, and remote control and remote regulating commands issued by the automatic system are recorded. The method comprises the following four testing steps of parameter setting, remote signaling verification, remote measuring verification and remote control verification. The remote signaling deflection generated by the hardware test environment is simulated through the four-remote signal simulation system, and batch generation of the change remotesignaling parts in a short time is achieved; the random function is adopted to generate the remote measuring parts within the reasonable range, and after communication is established, the remote measuring parts are uploaded to a testing system; and remote control commands issued by the testing system are recorded, the time of a functional test is shortened from at least five hours in the past to0.1 hour, the accuracy limit is increased, and the error rate is nearly decreased to be zero.

Description

technical field [0001] The invention relates to the technical field of power dispatching, in particular to a method for testing a new system using an analog four-remote signal generator. Background technique [0002] The EMS system (Energy Management System) is the basic system for power grid dispatching and operation. The rapidly developing power grid has continuously increased requirements for the EMS system. The existing system can no longer meet the development needs of the power grid, and a new system needs to be built. The EMS system has a certain service life. When the service life is reached, a new system must be built to meet the needs of the rapid development of the power grid. [0003] Before the new system is put into operation, it must undergo rigorous testing. One of the important test items is to verify whether the database of the new system is consistent with the system in operation. The test method currently adopted is as follows: build a test environment c...

Problems solved by technology

[0007] There are problems with the above method: 1. The speed is slow, and it takes 5 hours to test all the signals of a substation; 2, it is manpower-intensive, and at least two people are required to cooperate; 3, it is easy to make mistakes, because it is a long time of repetitive work, and misoperation may occur possible
