Abstract

The invention discloses an excitation system integral tester comprising an analog quantity acquisition unit, a wave recording processing unit, an operating system, a voltage modulating transformation unit and a variable resistor unit; the analog quantity acquisition unit employs an integrated analog quantity acquisition module; the input end of the analog quantity acquisition unit respectively collects a generator end voltage, a synchronization voltage, a generator stator current, an excitation transformer low voltage side secondary current and an excitation regulator silicon controlled rectifier trigger pulse in the excitation system; the output end of the analog quantity acquisition unit is connected with the input end of the wave recording processing unit; the wave recording processing unit employs a DPS high speed data processing core, and the output end of the wave recording processing unit is connected with input end of the operating system; the operating system employs an embedded windows system; the voltage modulating transformation unit employs a voltage regulator; the variable resistor unit employs a variable resistor. The excitation system integral tester can record testing data, can parse testing data, and can compare an excitation power cabinet output waveform with a pulse trigger waveform and parse the same, thus improving the power plant excitation system fault analysis determining capability.

Description

technical field [0001] The invention belongs to the technical field of a comprehensive detection test device for an excitation system of a power plant generator, and in particular relates to a comprehensive tester for an excitation system. Background technique [0002] As an important part of the power plant generator, the excitation system's operation stability and reliability play a decisive role in the safe operation of the generator set. In the static and dynamic tests of the excitation system, unit equipment wiring tests are currently used. The test wiring is messy and complicated, and the comparison function of test data and waveforms is missing, resulting in low efficiency, low safety, and inconvenient waveform comparison in field tests. . Contents of the invention [0003] The purpose of the present invention is to solve the above problems in the prior art, to provide a convenient, safe and efficient excitation system comprehensive tester, which has the function o...
