WOODWARD 8290-044 Electronic Speed Governor

WOODWARD 8290 - 044 is a product of Woodward's electronic speed governor (EPG), which is used for speed control of diesel, gasoline engines and gas turbines.

Features

High-precision speed control: It can accurately adjust the output according to the load changes of the engine or turbine to ensure stable operating speed and meet the speed requirements under various working conditions.

Multiple input and output interfaces: It can be connected with a variety of sensors, actuators and other control devices, receive speed feedback signals and external control instructions, output control signals to drive actuators, and realize complex control functions.

Adaptive control capability: It has an adaptive algorithm that can automatically adjust control parameters to adapt to different engine characteristics and operating conditions, reduce the workload of manual debugging, and improve the robustness of the system.

Fault diagnosis and protection function: The built-in fault diagnosis module can monitor its own working status and the status of the connected equipment in real time. Once a fault is detected, it can promptly issue an alarm signal and take protective measures, such as limiting the speed and cutting off the power, to avoid equipment damage.

Application field

Power industry: It is used for speed control of diesel generator sets and gas turbine generator sets to ensure the stability of the generator output frequency and meet the power supply requirements of the power grid. It is widely used in small power stations and emergency backup power supplies in remote areas.

Industrial field: such as self-contained power stations in factories, engines and gas turbines that drive large compressors, fans and other equipment, speed control is performed through 8290-044 to ensure the stable operation of industrial production processes.

Ship industry: Provide speed control for diesel engines and gas turbines of ships to ensure stable power output of ships during navigation and adapt to different navigation conditions, such as acceleration, deceleration, turning, etc.

Working principle

WOODWARD 8290-044 monitors the speed of the engine or gas turbine in real time through the speed sensor, and feeds the speed signal back to the speed governor. The speed governor compares the actual speed with the set speed, calculates the required control amount according to the deviation value through the internal control algorithm, and then outputs the control signal to the actuator, such as the fuel regulating valve, the intake regulating valve, etc., to adjust the fuel supply or intake of the engine or gas turbine, thereby achieving precise control of the speed and keeping the actual speed close to the set value.
