This paper describes the development of training simulator for Hadong fossil Power Plant. The simulator was developed to train operator, test new control Logic and evaluate alternative operating procedure for expert engineer of control system. The most control logics such as Siemens TELEPERM ME and GE Mark V are translated directly from microprocessors. Those HMI are also directly emulated. The simulation was performed by ProTRAX modeling software. The paper discusses the configuration of simulator and the simulation results of 30%, 50%, 75% and 100% normal rate load test.

The Simulation of Boiler System for Hadong Fossil power plant has been made by Korea Electric Power Research Institute (KERRI) in an attempt to develop Windown NT based full scope replica simulator for Hadong Fossil power plant, 500MWe once-through boiler. In the project KERRI developed Once Through, Super Critical type Boiler System, the core part of the Simulation and integrated the system with other process systems such as BOP System, and AUX System. This paper is to introduce the basic concept of the simulation for the Boiler System. It will also introduce PRO-TRAX System, for used as a modeling tool.

Significant amount of bottom ash has been stored in the pond site of Hadong coal power plant located at southeast region of Korea. In order to address strong environmental regulation that is going to be enforced in the near future, it is necessary to consume waste bottom ash stored in the pond site in a sustainable manner. In this research, the chemical and mineral characteristics of various sized bottom ash samples from Hadong coal power plant were analyzed using XRF, XRD, and particle size analyzer. According to the experimental results, the chemical compositions of bottom ash was slightly changed in terms of Al and Fe content. As the size of the bottom ash increased, cristobalite was observed as a result of crystallization. The mineralogical composition and its size distribution of powder type bottom ash indicated that significant amount of fly ash is included together with small sized bottom ash.

The Water usage is relationship which is close with the administrative cost from industrial facility. It is not easy to reduce a water usage. This research is the optimization of the waste water quantity which process waste water integration of the standard thermal power plant in system operate time. The turbine rotates by force of the steam and it produces an electricity. Demineralization Water is manufacture purity manufacturing equipment and it is supplied in power plant channel. We knew a possibility of reducing from pure control process. When it is reduced the Back Washing time, Rinsing time of the gravity filter and the activated carbon filter. Also, It is possible even from regeneration phase in Condensate Polishing Demineralization System. In addition, There is also the water which the drain of the sampling water for watching the condition of power plant process will be able to use. Integrates these processes it will be able to reduce an annual 30,000 ton degree. The research is want to use the fundamental data for the water curtailment of the power plant.

In order to understand changes of water temperature for thermal discharge of Hadong power plant in Gwangyang and Jinju Bay, it was analyzed for temperature data of representative season by MEM(Maximum entropy method) that is one of the spectral analysises. And due to understand effect of thermal discharge at each point, analyzed spectral data showed reactive energy rate of reference point by calculating energy from 24 time period to height frequency zone. As a result of spectral analysis, it showed that there were 9 points which are largely effected, 7 points which will be estimated, 6 points which is difficult to estimate, 14 points which rarely effected by thermal discharge.

This paper proposes the design and implementation of fluid flow generation system by using polypropylene(PP) water capture, which harvests electric energy from the kinetic energy of tidal current or water flow and drives the desired load, and applies it to the discharge drain of Hadong thermal power plant. This experimental system is composed of water captures, driving wheel, gear trains, 10[kW] synchronous generator, and three phase rectifying circuit which drives lamp load for test. The proposed water capturing system which is composed of water captures, rope and driving wheel, rotates as caterpillar according to water flow. This system is very easy to manufacture and more economical than another type of tidal current turbines such as conventional propeller and helical type. Also, we estimated the available fluid flow energy that can be extracted from the cooling water in discharge drain based on drain's cross-sectional area. Therefore, this paper confirms the validity of proposed fluid flow generation system with water captures and the possibility of its application for renewable energy generation in discharge drain of thermal power plant, from the obtained performance characteristic of this energy conversion system.

To investigate the impingement of fish on the traveling screens, fishes were collected from the traveling screens at Hadong Power Plant through the year of 1999. A total of 84 fish species were collected during the study period. The dominant species were Leiognathus nuchalis, Engraulis japonicus, Trichiurus lepturus and Takifugu niphobles. These four species accounted for 78.2% of the total number of individuals and 52.0% of total biomass collected. The number of fish species, number of individuals, biomass and species diversity indices fluctuated with the seasons. The number of species and biomass were high in April and August, and the number of individuals was high in April and July. However, the number of fish species, number of individuals and biomass of fishes showed low values in winter.

Cooling seawater of thermal power plant which amounts about 5 cms per 100 MWe has hydro energy of about 3,000 kW at the thermal power plant complex, but this useful hydro energy has not been developed. Therefore, the feasibility study on hydro energy development of three power plants located in the southern and western coast of Korea was performed. Three target power plants are Samcheonpo, Boryeong and Hadong thermal power plant. The design head to discharge cooling water by gravity and the head caused by tidal level in the southwestern coastal area, could be used for the production of electric power. The various alternatives were studied and technical feasibility and economical efficiency were clearly proved.

국내외에 아직 적용 실적이 없는 발전소의 해수방류수를 이용한 조류식발전시스템의 개발을 위하여 하동화력발전소 방수로에 시험용 조류식 발전시스템을 설계 및 제작하여 현장시험이 진행 중이며, 이를 확장하여 상업용 발전을 위한 총 개발 규모를 산정하고 경제성을 분석하였다. 조류식발전구조물의 형상 설계, 가이드 베인을 이용한 출력 조정을 통하여 방수로의 수류상태를 적절히 조절하여 설계하는 것이 가능할 것으로 판단되며, 조류식발전구조물 설치시 방수로의 수류특성 수치계산 결과로 판단할 때 발전출력에 의한 에너지 회수뿐만 아니라 조류식발전구조물의 단면축소 효과 및 수두손실이 방수로의 수위 변화에 상당한 규모로 영향을 주고 있음을 확인하였다. 조류식발전구조물 설치 이전의 유속 관측 결과를 이용하여 발전량을 산정한 경우 소수력발전 단가 적응시 경제성이 떨어지지만, 조류식발전시스템의 설치시 유속 증가 효과가 나타날 뿐만 아니라 가이드 베인 등을 이용하여 발전량 증대를 꾀하면 충분한 경제성을 확보할 수 있는 조류식발전시스템의 설치가 가능할 것으로 판단된다.
