Problems solved by technology

[0005] 1. In the system integration debugging, there is a lack of joint debugging organization, a standardized process from joint debugging preparation to the implementation of the plan, which is severely restricted by the frequent changes of the manufacturer's technical personnel and the power company's debugging personnel;
[0006] 2. The joint commissioning site is chaotic and the joint commissioning efficiency is low, so that the joint commissioning quality cannot be reliably guaranteed;
[0007] 3. Different manufacturers have different technical strengths and different testing conditions and means, resulting in uneven test integrity of test items and testing depth of protection devices and network performance;
[0008] 4. There is no corresponding plan and standard for factory joint debugging, the test tools are not standardized, and the test evaluation is not unified
[0009] Based on these factors, the current factory joint commissioning is only at the stage where the protection devices can be successfully connected and the communication can be successfully connected, and the basic functions can be realized. There is no in-depth test for network test, protection circuit, message monitoring and other items.

Embodiment Construction

[0057] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0058] A 220kV substation usually has more than 100 protection-related IEDs (protection devices, merging units, and intelligent terminals). With the addition of other IEDs such as measurement and control, the total number of IEDs in the substation will be even greater. In the laboratory environment, simulating the real environment of the site to carry out the factory joint commissioning test requires a large number of actual IEDs of various models to conduct auxiliary tests. Smart substations use optical fiber to transmit SV and GOOSE signals, so it is necessary to use digital simulation to test IED equipment. Digital simulation is divided into full simulation and partial simulation. If digital simulation is used for all IEDs in a substation, large hardware overhead is required, and the system formed will be very complicated, and the test configuration and o...

Abstract

The invention provides a secondary device integration and joint debugging method based on a virtual machine. The method comprises the steps that S1 the minimum test system of an intelligent substation is built according to the principle of guaranteeing the substation consistency; S2 the real test environment of the substation is built based on the minimum test system; by importing an SCD file, the configuration of the devices of the whole substation is acquired; data flows including SV flow and GOOSE flow in each device are acquired; the model of the whole substation is built through backstage, and the information of the devices of the whole substation is scanned; and S3 the minimum test system is used to integrate the device information and the definition and definite value of action behaviors to acquire a test item, a test program and a test result template. The factory-like joint debugging efficiency is improved. The joint debugging intelligent level is enhanced. The device debugging cycle is shortened, and the debugging environment is improved.

Description

technical field [0001] The invention relates to secondary commissioning of an intelligent substation, in particular to a virtual machine-based integrated joint commissioning method for secondary equipment. Background technique [0002] The secondary commissioning work of the intelligent substation is greatly restricted by the construction environment on site, including: (1) scattered equipment, which makes it very difficult to cooperate with the linkage test between equipment; (2) it is impossible to work outdoors in rainy and snowy days, dusty days, and at night (3) There are many holes and cable trenches in the construction site, and there are certain safety hazards; (4) It is obviously affected by the site environment, it is difficult to control the project debugging process, and the debugging quality will be affected to a certain extent. [0003] System integration debugging is an important link to find and solve problems in the whole test process of intelligent substati...
