WOODWARD 8290-185 EPG SPEED CONTROL Module

Features

High-precision speed control: Using advanced control algorithms and sensor technology, it can monitor the engine speed in real time, control the speed within a very small error range, and ensure that the equipment can operate stably under different load conditions.

Multiple control modes: It may have multiple control modes, such as isochronous control and proportional control, to meet the needs of different application scenarios. For example, in the field of power generation, the isochronous control mode can be used to ensure the stability of the generator output frequency; in the field of industrial drives, the appropriate control mode can be selected according to the actual process requirements to achieve precise speed control.

Fast response characteristics: It can respond quickly to sudden changes in load or other interference factors, quickly adjust the output to maintain the set speed, reduce speed fluctuations, and improve the stability and reliability of the system.

Flexible configuration options: It has a variety of input and output interfaces, which can be easily connected and integrated with various types of engines, actuators and other control systems. Parameters can also be adjusted through software or hardware settings to meet specific control needs.

Fault diagnosis and protection function: The built-in complete fault diagnosis system can monitor its own working status and the operation of related equipment in real time. Once an abnormality is detected, an alarm signal can be quickly issued and corresponding protection measures can be taken, such as limiting the speed, cutting off the power, etc., to avoid equipment damage and accidents.

Working principle

Usually, the module obtains the actual speed signal of the engine in real time through the speed sensor and compares it with the internally set target speed value. When the actual speed deviates from the set value, the controller calculates the required control amount according to the size and direction of the deviation and the specific control algorithm, and then outputs the corresponding control signal to the actuator (such as the fuel regulating valve, the intake control valve, etc.) to adjust the fuel supply or intake volume of the engine, so that the engine speed can quickly and accurately return to the set target speed value, and realize accurate control of the engine speed.

Application field

Power generation: It is widely used in diesel generator sets and gas turbine generator sets to ensure that the generator can run at a stable speed under different loads, thereby ensuring the stability of the frequency and voltage of the output power and meeting the power supply requirements of the power grid.

Industrial drive: used to drive engines for large compressors, fans, pumps and other industrial equipment, ensuring that the equipment can run at a constant speed under various working conditions, improving the stability and efficiency of the industrial production process.

Marine power: provides speed control for the ship's diesel engine or gas turbine to ensure that the ship can maintain a stable propulsion speed during navigation, regardless of the sea conditions or load changes, ensuring the navigation safety and performance of the ship.
