SCE 计算机控制的电站调节与控制设备

The Computer Controlled Power Plants Regulation and Control Unit, "SCE", has been designed by EDIBON to simulate and analyze the behavior of a power plant through two operating modes.

• Real mode: allows the analysis and data acquisition of the hardware under steadystate or transient conditions.
• Simulated mode: enables comparison with real operating data from power plants.

This dual functionality allows students and instructors to work with both realistic conditions and predefined models, facilitating a comprehensive study of regulation and control dynamics in electric power systems.

• Gate subsystem: Located at the top of the unit, it consists of a gate controlled by a motor. It regulates the simulated flow by adjusting the gate opening. A tachodynamo measures the motor speed, and a potentiometer records the gate position. The user can monitor key variables such as the control signal, motor speed, and gate position, simulating flow regulation in a real power plant. This subsystem is designed to directly control the flow toward the second subsystem, allowing analysis of its impact on power generation.
• Turbine-generator subsystem: Located at the bottom of the unit, this subsystem simulates the behavior of a turbine coupled to a generator. It can be connected to the gate subsystem via a switch that simulates their coupling. In this mode, the turbine speed depends on the gate opening, which in turn influences the generated electrical power. The subsystem can also operate independently for direct control analysis. It includes three types of electrical loads—resistive, inductive, and capacitive—each of which can be enabled or disabled via switches, allowing the study of system response under various load scenarios.

The front panel includes a unit diagram, test terminals for direct measurements, and switches to modify system operation. This setup supports both theoretical and practical analysis. The unit allows measurement of voltage, current, and turbine speed in an interactive and safe environment, with internally connected ground terminals across both subsystems.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
