GE IS215ACLEH1A Application Control Layer Module

Working Principle

Functional Characteristics

• Multiple Control Functions: It can realize excitation voltage control, excitation current control, excitation power control, and also has excitation system protection and monitoring functions to ensure the safe and stable operation of the excitation system.
• Rich Communication Interfaces: Equipped with dual Ethernet ports and two RS-232 serial interfaces, it can communicate with turbines, human-machine interfaces (HMI) and third-party systems, facilitating system integration and data interaction.
• Non-volatile Storage: It uses compact flash to store firmware, which can ensure long-term storage of firmware without battery backup, and guarantee that the module can still save key configuration information in case of power failure.

Advantages and Features

• High-performance Processing: It can be equipped with a high-performance processor, such as the 266MHz Pentium processor, which can quickly process complex excitation algorithms and meet the needs of fast and precise control of the generator excitation system.
• Redundant Design: Compatible with EX2100 redundant control racks, such as the IS200ERRB backplane, it has fault-tolerant capability. When some components fail, the system can still operate normally, improving the reliability of the system.
• Space-saving: Adopting a 2-slot 6U form factor design, it can provide rich functions in limited rack space, optimize space utilization, and facilitate installation and maintenance.
• Easy Maintenance: The compact flash of the module facilitates firmware updates and can reduce downtime. For example, after an American power plant upgraded its steam turbine excitation system with this module, remote diagnosis was realized through Ethernet, the excitation response time was shortened by 15%, and the downtime was reduced by 25%.

Application Fields

• Power Generation Field: Widely used in the excitation systems of generator sets such as gas turbines, steam turbines and water turbines, it ensures stable power generation of generators and improves power quality.
• Industrial Automation: It can be used in industrial drive systems to precisely control the excitation of motors, ensure the stable operation of power systems in industrial production processes, and improve production efficiency and product quality.
• Energy Management: In energy management systems, it helps optimize power distribution, improve energy utilization efficiency, and realize stable supply and reasonable allocation of energy.
