IS200EHPAG1D

Description

1. Product Overview

2. Product Parameters

Power Supply

• It is typically powered by a 24V DC power source. This stable power supply is essential for the proper functioning of the internal circuits of the board, providing consistent energy for signal processing, control algorithms, and communication functions.

Input Signals

• Analog Inputs: The board can receive multiple analog input signals related to the generator’s operating conditions. These include the generator’s terminal voltage, stator current, and field current. The analog signals usually have a standard range, such as 0 – 10V or 4 – 20mA, which are common in industrial control systems.
• Digital Inputs: It also accepts digital input signals. These signals can carry status information, such as the position of switches, the status of protective relays, or control commands from the overall control system.

Output Signals

• Control Outputs: The IS200EHPAG1D generates control signals to adjust the power supplied to the generator’s field winding. These signals are sent to power – control devices, such as thyristor bridges, to regulate the amount of current flowing through the field winding.
• Status Outputs: It provides status output signals that indicate the operating state of the board itself and the overall excitation control system. These signals can be used for monitoring and diagnostic purposes, allowing operators to quickly identify any potential issues.

Communication Interface

• It is equipped with an RS – 485 communication interface. This interface enables the board to communicate with other devices in the excitation control system, such as the main control unit, monitoring stations, or other peripheral devices. Through this communication, data such as input signal values, control settings, and fault information can be exchanged.

Operating Temperature Range

• Designed to operate within a temperature range of – 20°C to 60°C. This wide temperature tolerance allows it to be used in various environments, from cold outdoor power plants to warm indoor industrial settings.

3. Advantages and Features

Precise Control

• The IS200EHPAG1D offers highly precise control over the power supplied to the generator’s field winding. By continuously monitoring the input signals and using advanced control algorithms, it can adjust the field current with high accuracy. This ensures that the generator maintains a stable output voltage and frequency, even under varying load conditions.

Reliability

• Built with high – quality components and a robust design, the board is highly reliable. It can withstand electrical noise, voltage surges, and mechanical vibrations commonly found in industrial environments. This reliability reduces the risk of system failures and ensures continuous power generation.

Fast Response

• It has a fast response time to changes in the generator’s operating conditions. When there is a sudden change in load or other electrical parameters, the board can quickly adjust the field current to maintain the stability of the generator’s output. This fast response helps prevent voltage and frequency fluctuations, which are crucial for the quality of the electrical power supplied.

Flexibility

• The board allows for flexible configuration. Users can adjust various control parameters, such as gain settings, set – points, and control algorithms, according to the specific requirements of different generators and operating scenarios. This flexibility makes it suitable for a wide range of applications.

4. Application Areas and Application Cases

Application Areas

• Power Plants: In thermal, hydro, and gas – fired power plants, the IS200EHPAG1D is used in the excitation control systems of generators. It helps ensure that the generators produce a stable and reliable output of electrical power, which is then transmitted to the grid.
• Industrial Facilities: Large industrial facilities with their own power generation systems, such as manufacturing plants, refineries, and data centers, also utilize this board. It enables these facilities to have better control over their power generation and maintain a stable power supply for their critical operations.

Application Case

• In a hydroelectric power plant, the IS200EHPAG1D is installed in the excitation control system of a 200MW generator. As the water flow through the turbines changes due to seasonal variations or reservoir management, the load on the generator fluctuates. The IS200EHPAG1D continuously monitors the generator’s terminal voltage and stator current. When the load increases, it quickly adjusts the field current to increase the generator’s output voltage, ensuring that the power supplied to the grid remains stable.

5. Comparison with Competing Products

Control Precision

• Compared to some competing products, the IS200EHPAG1D offers higher – precision control. This results in a more stable generator output, which is especially important for applications that require high – quality electrical power.

Reliability

• GE’s reputation for quality and reliability gives the IS200EHPAG1D an edge over many competing products. Its ability to withstand harsh operating conditions and provide long – term stable operation is a significant advantage.

Communication and Configuration

• The RS – 485 communication interface and the flexibility in configuration make it easier to integrate into existing control systems and adapt to different application requirements compared to some competing products with more limited communication and configuration options.

6. Selection Suggestions

Generator Compatibility

• Ensure that the IS200EHPAG1D is compatible with the type and power rating of your generator. Consider factors such as the generator’s field winding requirements, input and output signal ranges, and control system architecture.

System Requirements

• Evaluate your specific excitation control requirements, such as the desired level of control precision, response time, and communication capabilities. Make sure the board can meet these requirements.

Environmental Conditions

• Take into account the operating environment of your application, including temperature, humidity, and electrical noise levels. The board’s operating temperature range and noise – immunity features should be suitable for your specific environment.

Budget

• While the IS200EHPAG1D offers high – quality performance, it’s important to consider your budget. Compare the cost of the board with your overall project budget and the features it provides.
