GE IS220PTURH1A

Product introduction

The GE IS220PTURH1A is a crucial component within the GE Speedtronic Mark VIe gas turbine control system. As a primary turbine trip pack, it serves as a vital link in ensuring the safe and efficient operation of turbines across various power generation and industrial applications. Its main function is to establish an electrical interface between the turbine control terminal board and one or two Ethernet networks, enabling seamless data transfer and control signals flow.

This module plays a central role in digitizing sensor signals from the turbine, which are then fed to the controller. By providing electrical isolation between the turbine sensors and the controller, it safeguards the integrity of the control system, protecting it from potential electrical interferences that could otherwise disrupt turbine operation. Whether in a gas turbine power plant or an industrial steam turbine setup, the IS220PTURH1A is designed to withstand the harsh environmental conditions typical of such settings, making it a reliable choice for mission – critical applications.

Core advantages and technical highlights

Electrical isolation and signal digitization: The IS220PTURH1A excels in providing electrical isolation, which is essential for protecting the sensitive control system components from electrical noise and surges that can originate from the turbine’s high – voltage and high – current operations. Simultaneously, it digitizes sensor signals, converting them into a format that can be easily processed by the controller. This digitization process improves the accuracy and speed of data transmission, enabling the control system to make more precise decisions regarding turbine operation.

Redundant Ethernet connectivity: With dual 100Mbps full – duplex Ethernet ports, the module offers redundant communication paths. In power generation facilities, this redundancy is invaluable as it ensures continuous data flow between the turbine control system and other components such as SCADA systems or operator workstations. If one network link fails due to a cable break, hardware malfunction, or network congestion, the second link automatically takes over, preventing any interruption in the monitoring and control of the turbine.

Speed detection and trip functions: Equipped with four passive magnetic speed inputs, the IS220PTURH1A can accurately detect the speed of the turbine. Its circuit sensitivity is remarkable, capable of detecting a turning gear speed as low as 2 rpm. This high – level sensitivity allows for precise determination of the turbine’s speed, which is crucial for both normal operation and safety – critical functions. The median speed signal generated by the module is used for two key purposes: speed control during normal operation to maintain optimal turbine performance, and as a primary overspeed trip signal. In the event of an overspeed condition, where the turbine’s speed exceeds safe limits, the module quickly sends a trip signal to the controller, triggering emergency shutdown procedures to prevent potential damage to the turbine.

Auto – reconfiguration and data storage: The module supports auto – reconfiguration, a feature that simplifies system maintenance and upgrades. Through GE’s ToolboxST software and its component editor, the IS220PTURH1A can automatically download baseload, boot load, firmware, and parameters from the controller. This ensures that the module is always up – to – date with the latest system requirements. Additionally, it has flash memory and RAM for data storage, which is useful for caching sensor data, storing configuration settings, and facilitating smooth operation during periods of network or controller unavailability.

Typical application scenarios

In gas turbine power plants, the IS220PTURH1A is at the heart of the control system. It processes speed data from the turbine’s rotation sensors, along with other sensor inputs such as temperature and pressure. Based on this data, it sends control signals to adjust fuel valves, ensuring that the gas turbine operates at the optimal speed and temperature for maximum efficiency and minimal emissions. In case of any abnormal conditions, such as an overspeed event or a sudden drop in pressure, it quickly triggers the appropriate safety mechanisms to protect the turbine.

Industrial steam turbines, commonly used in manufacturing plants for power generation and process heating, also rely on the IS220PTURH1A. The module monitors the steam turbine’s speed and other critical parameters, coordinating with the plant’s control system to meet the electrical and thermal demands of the manufacturing processes. For example, in a paper mill, the steam turbine may power the machinery while also providing steam for heating the pulp. The IS220PTURH1A ensures that the turbine operates smoothly, adjusting its speed and output as required by the changing demands of the production process.

Combined – cycle power plants, which combine the efficiency of gas turbines and steam turbines, benefit from the IS220PTURH1A in multiple ways. It plays a role in controlling both the gas and steam turbines, ensuring seamless integration between the two power – generating units. By accurately monitoring and controlling the speeds of the turbines, it helps optimize the overall power generation efficiency of the combined – cycle plant, reducing fuel consumption and increasing electricity output.
