Turbomachinery Control Solutions

The input and output (IO) modules for turbomachinery control applications provide powerful features for the high-speed control and protection of turbomachinery.
They have a highly reliable dual redundant configuration and an intermixed signal interface for handling both analog and digital data.

The IO modules come in two types, providing a comprehensive control solution for the power generation industry.
The Servo Module is designed to control turbine speed by interfacing with specific sensors and actuators to manipulate steam and fuel control valves.
The High Speed Protection Module is designed to protect the turbine from overspeed and other critical conditions by shutting steam and fuel valves.


  • Servo module for turbomachinery speed control
  • Protection module for turbomachinery protection
  • High-speed control at 5 or 10 msec intervals
  • Programmable protection logic
  • Dual redundant configuration
  • Analog-digital intermixed signal interface

Typical Control Algorithms:

  • Turbine startup & shutdown sequences
  • Inlet/Extraction value ratio control
  • Inlet pressure control & limiter
  • Extraction pressure control
  • Generator local control
  • Turbine protection - Burner management control
  • Boiler control

Customer's Voice
“We cannot imagine operating our plant without Yokogawa’s full-replica simulator.”

Nguyen Khac Son, CEO of Pha Lai Thermo Power Joint Stock Company, a subsidiary of the biggest power producer in Vietnam, Electric of Vietnam (EVN), said, “Through simulator training, our probationary and new operators can quickly learn how to operate our 300-megawatt coal-fired unit using exactly the same operator interface as the real system. Even experienced operators can effectively learn how to deal with every conceivable accident because it’s so realistic. We cannot imagine running our plant without Yokogawa’s full-replica simulator. It is essential not only for our plant but also for operators at EVN’s other plants. In addition, many power plant operators of PVN† come here for simulator training to learn how to operate a coal-fired power plant with Yokogawa DCS. So, our simulator is used to train most operators of the biggest and second biggest power producers in Vietnam.”

*Vietnam National Petroleum Group, also known as Petro Vietnam. PVN is the biggest economic group in Vietnam and owns power plants.

Measurement of NH3 Concentrations in Stack Flue Gas Using TDLS200

The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS200 Laser Analyzer is the solution to all these problems.

Geothermal Steam Pressure Monitoring

Geothermal power plants create electricity from geothermal energy. These power plants are similar to other steam turbine station; however their heat source is that of the earth's core. The created steam is used to turn the turbine for the production of electricity. Technologies include Dry steam, Flash steam and Binary cycle power stations with Binary cycle being the most common geothermal plant in current production. In the process of geothermal power generation the facility needs to monitor various processes, as in this case steam line pressure sits in remote from control room's location.

Cooling Tower

The term "cooling tower" is used to describe both direct (open circuit) and indirect (closed circuit) heat rejection equipment. Cooling towers are heat-transfer units, used to remove heat from any water-cooled system. The cooled water is then re-circulated (and thus, recycled) back into the system. Since the process water is re-circulated, the mineral concentration increases as a result of the evaporation.

The Use of an On-line Model for Site Wide Energy Costs Minimization

This paper describes the tasks performed together with Soteica, by using an on-line model, to help achieve site wide energy costs minimization.
A detailed model of steam, fuels, electric, boiler feed water and condensates system has been built, contemplating all the real constraints and degrees of freedom for their operation. The electric power system is also modelled as it interacts with the steam production and usage. Such a model is continually validated with live data. A continuous calculation of equipment efficiencies is done as part of the performance monitoring activity of the model that is running as a service.

Monitoring Mercury Control in Coal Fired Power Plants using ORP

Current trend for increasing mercury awareness throughout the public sector has caused the government to take action. Recently, the Environmental Protection Agency (EPA) has focused their efforts on controlling mercury levels produced in various coal fired power plants. Based on information from several case studies, the EPA developed the Mercury and Air Toxics Standards to cut back mercury emissions. The most popular technology utilized by coal plants to meet the new standards is a scrubber which cleans the off gas from the combustion process. ORP sensors can further monitor the effluent from these scrubbers to ensure optimal mercury emission levels are achieved. By closely monitoring the mercury concentrations in the effluent, plant managers will be able to easily confirm their plants are meeting the EPA's standards.

Why Yokogawa? Migrating from a Honeywell Platform to Yokogawa's CENTUM VP

Honeywell and Yokogawa have both been producing Distributed Control System (DCS) platforms for decades, and both are very active in this area. In 1975, Honeywell introduced its TDC2000 platform and Yokogawa brought out CENTUM. These two competing systems emerged from a similar place, oil refining and petrochemical industries, so they started out with similar basic concepts and use cases in mind.
