“…This difference can be gauged by isentropic turbine efficiency defined by For turbine with regenerative feed heating, the thermal efficiency is the significant criterion. It is defined as the ratio of power output to heat added to the cycle from external sources [25] [26]. (11) The heat rate traditionally has been used and is still used for the same objective as thermal efficiency, which is applied in these rules [25] [26].…”

The performance capability of the steam turbine under factory conditions will experience changes that can be caused by operating or environmental factors. Therefore, it is necessary to analyze the performance of the steam turbine during the actual condition so that it can be compared with the performance of the steam turbine from the manufacturer using mass and energy balance equations on HP heater #1 and deaerators and iteration methods. The research was conducted by looking at the phenomena that occur in the steam turbine using mathematical models and theories when the unit operates according to the heat balance design parameters. Feedwater flow from the calculation of the iteration method based on the equation of the water heater obtained a value of 17,961.58 kg/h. The performance steam turbine experienced a decrease in efficiency with a value for isentropic efficiency of 72.73% down 6.54% from the design value of 79.27% and thermal efficiency of 26.88% down 1.75% from the design value of 28.64%. Meanwhile, the steam rate value of 5.03 kg/kWh increased by 0.44 kg/kWh from the design value of 4.59 kg/kWh, and the turbine heat rate of 3198.83 kcal/kWh, an increase of 196.08 kcal/kWh from the design value of 3002.75 kcal/kWh.

“…The hotter the cold source temperature, the less the efficiency of the NPP. Indeed, not only a rise in the temperature of the cold source make the condenser's cavity saturated pressure higher that deteriorates heat exchanges between the cold water and the steam coming from the BP turbine [14], it also affects the performance of the BP turbine [15]. Furthermore, the condenser's cavity saturated pressure also depends on the load.…”

The penetration of intermittent low-carbon energies in the French electric mix challenges the need of enhancing the manageability of the French nuclear fleet. Most of the French nuclear reactors have been devised to do load-follow operations in order to ensure the supply and demand balance anytime. However, it has been shown that the less the share of electricity production from nuclear energy (which would be mainly compensated by the development of wind and solar energy), the more load-follow transients will be planned to manage summertime peak of electric over-production or conversely winter season peak of underproduction. A coupling between the secondary loop and the cooling circuit of a pressurized water reactor has been implemented in addition to a simulator oriented French 1300 MW reactor model. We present here our modeling of the steam turbines, the moisture separator, the water reheater and the condenser for a typical P'4 French nuclear reactor provided with an open-loop cooling circuit. As we study off-design load conditions, we simulate a load transient based on real electricity production profile done in the past few years. We compare the temperature of the water withdrawn from the cold source downstream of the plant measured on site and the one we calculate from our model.

“…Hydropower is an attractive renewable energy choice because it provides various benefits over conventional electrical power. Because they do not require high temperatures to function and don't rely on expensive fuel sources like fossil or nuclear, hydroelectric facilities offer cheap operating and maintenance expenses [12,13].…”

The Hydro-PowerStation is one of the keys (important) sources of electricity, and it has a digital governor, which improves production efficiency over mechanical governors. This research looked at the hydraulic turbine, found flaws such as oil leakage from the pumps utilized, calculated the amount of energy consumed, and worked to reduce it by measuring the losses and monitoring the poor process during periods of high water load of up to 83%. As a consequence of the research, it was discovered that the amount of energy consumed had decreased by 20%, by employing well-made, effective pumps for each unit according to its use, oil leakage in all units is reduced.
