Problems solved by technology

The protocol provides users with many options, but for power system application personnel, there are too many configurable parameters, and it is difficult to grasp the selection of parameters and the selection of application functions
[0003] According to the search results, it is found that there is no complete protocol analysis and protocol testing software in China, and the existing similar software in China is facing three problems: 1. There is no complete and comprehensive protocol testing items, and the protocol testing items cannot be configured; 2. The weight of the test item cannot be customized, and it cannot be tested automatically, requiring manual intervention by the tester; 3. Only the correct response can be tested, and various errors in the communication cannot be simulated

Embodiment Construction

[0021] figure 1 It is a structural diagram of the power network protocol analysis and testing system in the present invention. The system includes a portable computer on which a set of protocol analysis and testing software is installed, and also includes a switch and serial port expansion equipment. The first protocol is a serial protocol , through the serial port expansion equipment, the test system can communicate with the sub-station under test serially, and carry out the test implementation of the first protocol. The second protocol is the network protocol, and the test system can communicate with the sub-station under test through the switch. Implement the tests for the second protocol.

[0022] Figure 4 It is a schematic diagram of the main functional modules of the system in the present invention. The portable computer includes the following functional modules:

Abstract

The invention discloses a power grid protocol analysis and test method, which is characterized by comprising the following steps: 1) listing test items for a power grid protocol test; 2) setting test item weighting for the power grid protocol test; 3) setting automatic test items for the power grid protocol test; 4) testing the protocol; 5) recording in the test process and monitoring in the whole course; and 6) automatically obtaining a test conclusion and automatically printing a test report form. Through the steps, the power grid protocol analysis and test method further strengthens the consistency of communication procedure between various automation manufacturers and various dispatching ends, reduces working time for debugging an automation substation end and a main station end, avoids cycle data transmission protocol defects caused by artificial factors or understanding errors, and is favorable for automation communication procedure software management.

Description

technical field [0001] The invention relates to a power grid protocol analysis and testing method, which belongs to the technical field of power systems. Background technique [0002] IEC60870-5-101 (version 2.0, 2002) and IEC60870-5-104 (version 1.0, 2000) have been widely used in my country since their release. my country's power industry has released the DL634.5101-2002 and DL634.5104-2002 agreements, and it is indicated that they are equivalent to IEC60870-5-101 (version 2.0, 2002) and IEC60870-5-104 (version 1.0, 2000). of. Because the protocol covers basic telecontrol tasks such as telemetry, remote signaling, remote control, remote adjustment, time synchronization, parameter downloading, and file transmission, and the transmission control mechanism of IEC60870-5-101 / 104 is perfect, its application range is very widely. The protocol provides users with many options, but for power system application personnel, there are too many configurable parameters, and it is diff...
