Abstract

The invention relates to an automatic control system of a gas turbine generator set. The system adopts a plug-in board structure, and includes a main channel and a subsidiary channel. The main channel comprises a secondary power supply, a single chip microcomputer, an optical coupling input isolation circuit, a photovoltaic relay output isolation circuit, a data acquisition circuit, and an electromagnetic valve drive circuit. The subsidiary channel adopts a sequential logic circuit to realize the control function. The system provided by the invention completes cold start, process startup and programmed start by receiving external instructions, monitors the air inlet temperature, the exhaust temperature, the lubricating oil pressure, rotation speed and other over 30 operating parameters of the generator set during working, accomplishes over 20 fault protection and alarm functions, and transmits the exhaust temperature, the rotation speed, the fault and other information to a display control device, thus realizing the human-computer interaction function.

Description

technical field [0001] The invention relates to an automatic control system of an intermediate frequency synchronous generator, in particular to an automatic control system of a gas turbine generating set, which belongs to the field of intermediate frequency (400Hz) power generation, and the applicable power generation frequency is 400Hz. Background technique [0002] The intermediate frequency generating set is mainly used in aircraft and ground equipment in China due to its advantages of small size and light weight. The main source is imported equipment, which has problems such as narrow procurement channels, difficulties in after-sales guarantee, high quality, large volume, and imperfect functions. At present, there are no mature products on the market in China, and only some products are under research. The products under research generally have problems such as poor compatibility, poor real-time performance, low reliability, low circuit integration, loose structure, lar...
