Korea South East Power Co. KOSEP , a wholly owned subsidiary of the government-owned Korean Electric Power Company, constructed two new MW supercritical coal-fired units in Yonghung, Korea to generate highly-efficient, environmentally-friendly electricity. To ensure that the commissioning process for its new plant went smoothly, KOSEP turned to Yokogawa and its TechComm Simulation subsidiary for a full-replica training simulator solution. To achieve these objectives, the simulator was required to fully simulate DCS functions and emulate turbine, generator, and electrical control functions.
The simulator was delivered on-schedule to the site in September , twelve months before the boiler was to be fired up for the first time. This enabled thorough validation of the control configuration prior to DCS installation at the site, thereby minimizing the final tuning work.

A significant number of potential plant trips and situations where there was potential for damage to the plant were identified and resolved before the initial plant startup, ensuring a safe and smooth plant commissioning process. The thorough control system validation on the simulator also provided a suitable training environment for plant operators. The simulator aided in the initial training for plant operators and refresher training for experienced operators under a wide variety of normal, abnormal, and emergency operating conditions.
In parallel with DCS commissioning, KOPEC plant operators were well trained under the new control environment, reproducing custom-made flexible operating scenarios on the simulator. This avoided mistakes that could have occurred if the operator had not been familiar with the new system, thereby ensuring safe and smooth plant operation.
The simulator also has the flexibility and expandability to accommodate future improvements in plant performance.

The working principle of thermal power plant operation depends on Rankin Cycle. In a thermal power plant, coal is coming from coal storage and burnt in the boiler. It converts water into steam. This steam is expanded in the primemover i. Those control reserves are usually provided by thermal power plants. Particularly in times of high shares of fluctuating renewable feedin, thermal power plants are turned off or operated at minimum load to avoid electricity production at low electricity prices.
Mathematical model of this process enables operator to optimize the control of the actual plant and the designer to optimize the design of the future plants. There are many units that are situated in the main technological chain of the thermal power plant. In this paper, research results of modelling and simulation of thermal power units are reviewed. Numerical simulation of solar chimney integrated with exhaust of thermal power plant H. AlKayiem1, K. A simulation has facility to acquire the value of temperature and pressure which are sensed by a temperature sensor and pressure sensor respectively.
In this Simulation we can supervise high and low level position of level sensor available at mini thermal power plant setup.
Thermal Power Library
Highfidelity dynamic simulation of thermal power plants. It includes complete model libraries to build plantspecific. Three power plant models are presented, which are used as reference cases: a dynamic model of a combined cycle power plant CCGT , a model of a oncethrough supercritical coalfired power plant, and a model of a concentrated solar power plant CSP.
Both subcritical and supercritical pulverized coalfired power plants were used in the simulation. Figure 1 Computational algorithm of developed power plant model.
