Description

technical field [0001] The invention belongs to the field of power grid stability simulation modeling analysis, relates to a gas turbine speed governor modeling test technology, in particular to a gas turbine speed governor servo system control parameter testing method and a system thereof. Background technique [0002] The gas turbine generating set is the unit with the fastest response to the frequency regulation of the power grid, and plays an important role in maintaining the stability of the power grid. When the grid frequency changes, the generator set immediately reverses the power adjustment through the gas turbine governor to achieve the purpose of stabilizing the grid frequency. The simulation calculation of power grid stability requires an accurate gas turbine governor simulation model, and its model and parameters must be tested, identified and verified through experiments. At present, most of the gas turbine generator set governor control equipment is imported ...

AI Technical Summary

Problems solved by technology

At present, most of the gas turbine generator set governor control equipment is imported from abroad. For the protection of intellectual property rights or to prevent random changes in control parameters, the governor servo system equipment is often packaged, and the output signal of the servo system cannot be tested or changed, let alone understood. Internal control parameters and their control performance

At the same time, there are many types of speed governor servo system equipment in the market, and the functions and performance of the products are uneven, and its control performance cannot be understood, so it is necessary to conduct actual measurements
