Problems solved by technology

The advantage of the state sequence is that the output state of the entire test can be clearly defined, but the disadvantage is that it cannot establish an intuitive connection with the protection logic, and the tester needs to extract the detection elements before creating the test

Abstract

The present invention provides a relay protection test system and method, the relay protection test system includes a test module and a tester, the test module sends test parameters and control instructions to the tester; the tester outputs test signal and receive the action feedback signal of the device under test, compare the test signal output by the tester, the expected action result with the action feedback signal, and realize the relay protection test; the test module is used to The meta library constructs a test logic diagram, and generates a standardized logic test state sequence according to the logic diagram. The system provided by the invention enables users to establish a test logic model simply, intuitively and accurately so as to conduct professional tests of complex functions and logical relationships, which is the development direction of the specialization and standardization of relay protection testing.

Description

technical field [0001] The present invention relates to a system and method in the technical field of relay protection testing, in particular to a logic diagram-based relay protection testing system and method. Background technique [0002] The logic diagram of relay protection is a graphical method to describe the protection function through logic input (such as starting element, direction element, etc.), logic output, AND gate, OR gate, NOT gate, time element, logic line, etc. It is characterized by the ability to present complex logical structures clearly and intuitively. [0003] The state sequence is to divide a complete experimental process into several continuous and independent states, and each state describes various information of the state through a series of parameters (such as voltage, current, frequency, binary input, binary output, duration , trigger conditions for entering the next state, etc.). Relay protection test software has widely used this method to ...
