PM3398B-6P-1-3P-E Controller Hardware

PM3398B-6P-1-3P-E is suitable for DEH hydraulic control of large thermal power generating units. The function of the oil supply system is to provide high pressure anti-fuel oil from which servo actuators are driven, and the actuators respond to electrical command signals sent from the DEH to regulate the opening of the turbine valves. The critical shutdown system is controlled by the shutdown parameters of the turbine, and when these parameters exceed their operating limits, the system closes all the steam inlet valves of the turbine, or only the regulating steam valves.

PM3398B-6P-1-3P-E guarantees that the normal operation of the turbine unit will not be affected in the event of a failure of any of the components in any of the servo loops. The regulating valve, regulating valve actuator, electro-hydraulic servo valve, servo valve drive circuit, etc., which are not considered in the traditional triple redundancy system and are the most prone to failure in actual operation, are all designed as multiple redundancy.

PM3398B-6P-1-3P-E Functions:

●Speed control: ramp-up, overcritical, and variable speed control functions
Compressor control: constant air pressure, constant air volume, static lobe control, and anti-surge control.
●Interlock protection: start interlock, overspeed protection, anti-backflow protection, stop output
●Auxiliary control: main body monitoring, auxiliary machine control
