Control and protection of turbine units
Gas turbine control unit (G-TECH)
After years of studying the DCS control systems of gas turbines and by reviewing and modelling the General Electric 5001 and 5002 control and protection systems and optimizing them, the company was able to develop its comprehensive control and protection system called G-tech (stands for “Gas turbine control technology”) in November 2011. G-tech is compatible with many types of turbines such as Hitachi, BBC, Siemens, etc.
The G-tech includes comprehensive turbine control and protection system, which was first planned for gas units and specially designed for GE turbines 5001 and 5002, and then has been adapted and optimized for using in other kinds of turbines (Hitachi, BBC, Siemens, etc.). These products can be extended to other gas turbines, regardless of their applications as turbo generator, turbo-compressor and turbo-pump. This comprehensive technology has been developed by studying different types of turbines and adapting the initial designs for a wide range of customers with different turbine types and a variety of applications.
Optimization of turbine controllers
Based on our technical proficiency, one of the services which are provided by HANI ENERGY Company is the performance test and inspection of the turbine controller. After examining each controller and its performance coefficients, optimization is applied to the turbine, which reduces the costs of O&M (operation and maintenance) in the mechanical unit.
At first, we audit and investigate the turbine controller’s working flow pattern in different operating modes and conditions of the turbine. Next, we examine all controller components one by one, and finally, the coefficients and their overall performance will be reviewed. This can have a significant impact on the optimization of the turbine performance and reduction in the O&M (operation and maintenance) cost of the mechanical unit.
Control and protection of steam and combined units
By increasing of G-tech capabilities, we extend the scope of this turbine controller to a variety of steam turbines, including the LMZ Russian turbine generators. To obtain control technology for steam units, HANI ENERGY performed numerous research projects in steam plants that cover a wide range of processes. The following processes in a steam plant are among the main units included in our controllers:
- Turbine control of steam units
- Control of fuel cycle, air and vacuum (fuel, tail and suction)
- drum level control with three-parameter algorithms
- Superheat Steam Temperature Control (ABZ)
- Burner Controls (Complete BMS Cycle Includes Logic and Control)
- Condenser level control
- Injectors control
- Control of the cooling cycle
- Control of full cycle of water and steam and related tanks
- Increase the safety and reliability of the unit by implementing 2 of 3 logic.
- The simpler product of this family is named G-tech 401, as an alternative to every electronic governor controller, to install and control small steam turbines on turbo steam pumps, etc.
