Steam turbine is a device that converts the thermal energy stored in pressurized steam into mechanical energy.

It can be said that most of the world's power plants use a steam turbine in a thermal power plant. In the US, up to 90% of electricity is generated from this method, and in Iran this figure is above 90%.

Steam turbines are powered by a boiler, which produces steam boilers with high pressures (sometimes even more than 100 times) and sends them to the turbine, and the turbine supplies it to mechanical energy, and then to the generator to energy Electric converts.


Controlling systems
Controlling systems control the flow of fluid in the turbine to achieve the following:
Maintaining constant speed of the shaft at all times
Maintain constant steam flow among turbines
Maintain constant steam pressure in all flows
Limiting the Produced Force
To control the above parameters, the controller system has four main operating arms that cause changes in the operating point and process:
Speed ​​controller
Booster
Changing the speed
Connection mechanism

According to certain criteria, steam turbines can be classified into categories, these criteria are:
1. The number of stages of operation: turbines are divided into single-stage or multi-stage types.
2. Mode of operation: Two types of blows and reactions.
3. Type of shell: There are single or multiple turbines.
4. Type of shaft and shaft arrangement: The turbines are divided into tandem and cross-type types.
5. For Flow Flow: Turbines are divided into Axial Flow, Radial Flow, and Tangential Flow.
6. Steam entry and steam outlet conditions: Turbines have noncondensing, condensing or back pressure, mixed pressure and reheat types.

This product is specifically designed to replace the 505 TurboWatcher Controller (which is designed for high-speed and sensitive rotary machines).

In this product, all the needs of steam turbines, including control and protection, have been anticipated and the system parameters are in line with the Woodward controller.
 
This system is a perfectly industrial and dust-resistant design that is suitable for industrial applications. In this system, the three processors are simultaneously active and have independent protection from the main controller and reliability even higher than the American sample.
Features of this system include:

Controller system with adjustable parameters for each working environment and every steam turbine
Upgraded control panel
Structure and function easy
Ability to change and set parameters remotely
Independent speed protection system
Connect to LAN cable
Level of insulation against moisture and sulfur

Steam's executive team consists of 10 top engineers who have high education in electrical engineering, electrical engineering control, electrical engineering, mechanical engineering and computer engineering, as well as a long history of turbine control and Their performance has led to the creation of a control system based on DCS technology to control boiler and steam turbine systems and now controls 640 megawatts of power generation in the country.
This unit is managed directly by the company's CEO.
