Reliable and efficient performance: adopting advanced processor and high-speed digital signal processor (DSP) to ensure the stability and high efficiency of system operation.

Advanced control and monitoring functions: capable of processing and executing various control logics, real-time monitoring of gas turbine operation status, including temperature, pressure, speed and other key parameters.

Durable design: adapted to the harsh requirements of industrial environment, with anti-vibration and anti-electromagnetic interference features.

Fault diagnosis and protection functions: Built-in multiple fault diagnosis and protection mechanisms, such as over-current protection, short-circuit protection, etc., to ensure timely response and measures in abnormal situations.

Rich human-machine interface: provide intuitive and easy-to-use operation interface, which is convenient for users to carry out parameter setting, status monitoring, fault diagnosis and other operations.

System Functions

Real-time monitoring: real-time monitoring of various operating parameters of the gas turbine to ensure that the equipment is in the best operating condition.

Automatic control: according to the preset control logic and algorithm, automatically adjust the operating parameters of the gas turbine, such as the fuel flow rate, gas intake, etc., in order to achieve the most optimal operating efficiency.

Safety protection: automatically take protective measures, such as shutdown and alarm, when abnormal conditions are detected, such as over-temperature, over-pressure, over-speed, etc., in order to prevent equipment damage and accidents.

Data recording and analysis: Record and store the operating data of the gas turbine to provide a basis for subsequent fault diagnosis, performance analysis and optimisation.
