Hydraulic turbine automatic governor control system based on computer control

Abstract

The invention discloses a hydraulic turbine automatic governor control system based on computer control. The system comprises a computer which is connected with a single chip microcomputer controller through a data line. The computer is connected with a wireless radio frequency transceiver module through a GPRS network. The input end of the single chip microcomputer controller is electrically connected with the output ends of a power transmitter module, an external grid frequency monitoring module, a filtering module and a power supply. The output end of the single chip microcomputer controller is electrically connected with the input ends of a signal grounding module, a signal amplification module, a position monitoring module and a liquid level monitoring module. The single chip microcomputer controller is electrically connected with a database module and a dynamic simulation module. The output end of the signal amplification module is electrically connected with the input end of an electro-hydraulic servo valve. The system provided by the invention has the advantages that a computer can carry out remote control on a hydraulic turbine automatic governor; the operation of a hydraulic turbine can be monitored in real time; and the intelligence degree is high.

Description

technical field [0001] The invention belongs to the technical field of governor control systems, and in particular relates to a computer-based automatic governor control system for water turbines. Background technique [0002] At present, under the background that fossil energy is non-renewable and its use is extremely easy to cause environmental pollution, countries around the world regard the development of renewable energy as an important measure to revitalize the economy, and China is the same. Hydropower is the renewable energy that countries give priority to develop. However, my country's hydropower reserves rank first in the world, mainly enriched in large rivers, and large-scale hydraulic turbines are needed to effectively develop them. The most important part of the power generation of the hydro-turbine unit is the automatic governor part. Because the output power of the hydro-generator set must be adjusted continuously with the continuous change of the power consum...

Problems solved by technology

[0003] The control system of the automatic governor of the current water turbine unit is not highly intelligent, and can only be adjusted. When a fault occurs, the fault point cannot be determined in time. The electronic equipment in the control system is extremely susceptible to electromagnetic interference. For the precise operation of the water turbine unit is a big hidden danger
