Abstract

The invention discloses a generator exciting function simulation test system, comprising an industrial personal computer and an excitation adjusting machine; the industrial personal computer is provided with a human-machine interface module and a communication module; through an exchange, the communication module of the industrial personal computer transmits analog and switch information to the excitation adjusting machine and receives a control feedback signal sent by the excitation adjusting machine; the excitation adjusting machine is provided with a communication interface, the communication interface is connected with the exchange, receives analog and switch information sent by the industrial personal computer, and sends control feedback information to the industrial personal computer. Existing hardware in an excitation system is made full use, adding extra hardware equipment to a test is not required, the hardware circuit is simplified, traditional three-phase protective inspector and cable wiring are omitted, the test operation process is simplified, and feedback and judgment can be made automatically according to test results.

Description

technical field [0001] The invention relates to a generator excitation function simulation test technology, and belongs to the technical field of industrial control. Background technique [0002] The excitation system is an important part of the generator, and the performance of each unit directly affects the reliability and stability of the generator operation. The control function of the excitation regulator is the core part of the excitation system. The function simulation test of the excitation system is an important test for the control function verification of the excitation regulator. [0003] The traditional test method of excitation system function simulation is to use a three-phase protection calibrator to send voltage and current to the regulator to simulate generator excitation special PT, instrument PT, generator stator CT, generator rotor CT, synchronous transformer two Secondary side input, simulate possible generator working conditions, and check whether th...
