Abstract

The invention discloses a dynamic simulation test device and test method for a static variable-frequency starting system of a gas turbine generator. The device comprises a synchronous motor-generatorset, a static variable-frequency starting system, a voltage source type frequency converter system, a synchronous generator excitation system, an automatic quasi-synchronization device and a load resistance box; the input end of the synchronous motor-generator set is connected with the output end of the voltage source type frequency converter system; the output ends of the synchronous motor-generator set, the static variable-frequency starting system, the synchronous generator excitation system and the automatic quasi-synchronization device are connected with the load resistance box; the inputends of the static variable-frequency starting system, the voltage source type frequency converter system, the synchronous generator excitation system and the automatic quasi-synchronization device are connected with an alternating current power supply. The test device and method have the advantages that the problem that a gas turbine generator static variable-frequency starting dynamic simulation test device and method are lacked in the prior art is solved, and testing and simulation are conducted through the dynamic simulation test device.

Description

technical field [0001] The invention relates to the technical field of gas turbine generator set control, and more specifically relates to a dynamic model test device and a test method for a static variable frequency starting system of a gas turbine generator. Background technique [0002] At present, the development and utilization of natural gas is the only way to move towards ecological civilization. Gas turbine power generation is an important part of clean energy power generation technology, which is of great significance to actively promote the national energy revolution. [0003] However, there are many problems in the static variable frequency starting equipment of gas turbine generator sets. For example, most of the static variable frequency starting systems of gas turbine generators are imported equipment, and the operation and maintenance process relies too much on equipment manufacturers. Due to the technical blockade of the equipment, the cost of replacing spare...
