Performance And Economic Research Of The Second Circuit In Nuclear Power Unit

So far, rely on the development of the energy industry of the people of the world more and more energy, petrochemical industry as a traditional energy step by step decline, and as a new energy efficient environmental protection, nuclear power has become increasingly accepted. China in recent years the rapid development of the cause of nuclear power, the nuclear group, China Guangdong Nuclear Power Group and the national power investment group as the representative of the nuclear power construction company is rising rapidly,which makes the Chinese inland nuclear power increasingly large scale. Although nuclear energy is a green, economic, environmental and energy, and reserves are very large, but we also need to consider the economic power of nuclear power, the input output ratio of nuclear power. To address this concern, we have combined the use of nuclear energy and economic principles to develop a completely new approach to the study of the thermal economy of nuclear electric motors. Prior to this, more scholars use of thermal economics to analysis and improvement of waste heat power generation and thermal power system, not a lot of people use thermal economics to study the nuclear power plant thermal system. Under this situation,I based on the thermodynamic parameters of the data China Guangdong nuclear power group HongYanHe nuclear power project group of two circuit, analysis of the HongYanHe nuclear power project group of two loop thermal systems using the method of matrix pattern,rationalization proposals from the perspective of their analysis are given in the end.Under rated conditions, the actual operation parameters and the environmental parameters of HongYanHe nuclear power station unit by cnpec colleagues; the calculated enthalpy data is obtained through the analysis of water vapor research program, energy values obtained on the basis of using the method of energy analysis; research 1000 MW HongYanHe nuclear power plant thermal system based two loop under the operating mode of each subsystem of energy efficiency, energy consumption per unit of energy, loss and energy loss coefficient, through the analysis of the data about the heat of HongYanHe nuclear power plant60 subsystems of utilization, calculate the HongYanHe nuclear power unit in the 90% power operation and 70% power operating conditions of energy efficiency and energy loss data. To complete the data comparison in 100% rated operating conditions of the above data and nuclear power units in HongYanHe, eventually can break through the subsystem of the Suitable operating conditions of this problem, further through the calculation to improve the thermal efficiency of the unit.On the basis of the above, this paper expounds the energy cost calculation equation and the unit thermoeconomic cost calculation equation is through the thermaleconomics model under the theory of matrix out, followed by the matrix equation of the software for HongYanHe nuclear power units in 100% rated power under the condition of energy cost and unit energy cost with the unit thermoeconomic cost and energy cost data can get out, and then summed up at rated operating conditions and the overall distribution of the thermodynamic process of HongYanHe nuclear power plant, the energy loss of every subsystem of nuclear power units were checked. After the thermal system of HongYanHe nuclear power plant in90% power and 70% power operating conditions with energy cost, energy cost and data unit data unit thermoeconomic cost data, and these data were compared by standard power operation state of the data, find out the cost of nuclear power plant thermal economics change with the change of working condition the rules, finally obtains the reason.Finally, the thermodynamic parameters and the input-output cost comparison, find out the key factors of nuclear power plants have an important impact on economic operation,analyzes this improvement, finally to provide reliable support for enhancing the performance of the nuclear power plant two loop thermal systems.
