A testing method for power system state estimation software

Abstract

The present invention relates to a testing method for the state estimation software of a power system. The method comprises: constructing a testing environment for the state estimation software; performing power flow calculation to obtain a convergent basic power flow section; setting disturbance for the basic power flow section, determining the disturbance section, and calibrating Test the feasibility of the disturbed section, if the verification is passed, generate a test case; follow the E language specification, generate data files according to the test cases; obtain the comparison results of the data files through comparison; evaluate the comparison results, and draw the test conclusion. The invention provides a third-party testing method for software suppliers and customers, and effectively improves the efficiency and accuracy of state estimation software testing.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a testing method for power system state estimation software. Background technique [0002] Power system state estimation is to solve the state quantity describing the steady-state operation of the power grid-bus voltage amplitude and phase angle based on the power grid model parameters, tie-line connection relationship, and a set of redundant telemetry values ​​and remote signal switch status. The estimated value of , and solve the estimated value of the measurement, detect and identify bad data in the measurement. State estimation is one of the core application functions in the power dispatching automation system. The redundancy of the real-time measurement system is used to improve the data accuracy and provide a complete and accurate set of real-time operation mode data of the power grid for other application functions. [0003] As a testing method based on proving th...

Problems solved by technology

The basic conditions of the test are poor, the power grid model is generally too small during the test, and the authenticity of the data is poor; the test case is temporarily prepared according to the acceptance outline, and the test effect is severely limited

This test method, which relies on manual operation and empirical judgment, has strong subjectivity and one-sidedness, poor ability to test the correctness of test results, requires high professional level of testers, and has a long test cycle.

However, due to the lack of professional content related to state estimation, general software testing methods are difficult to be directly applied to the testing of state estimation software.
