Abstract

This research complements the shortcomings of PLTB, namely by adding a Monitoring System to the Wind Power Plant at Batam State Polytechnic. By addition of sensors, installations, and a control panel containing instruments for monitoring wind conditions, Savonius turbine rpm, and pico-generator output electrical characteristics. The method used is conventional, starting from mechanical design, program development, and installation to testing. This study's preliminary results indicate that wind at the PLTB Polibatam location is not continuous. It does not occur, even though the maximum wind speed can reach 8.9 m / s. The implementation of the savonius-type wind turbine in this study can generate electricity around 87.83 kW / week or about 0.61 kW / hour.

Abstract

Gas and steam power generation units often experience changes in load according to the requested electricity needs. Changes in generator workload will also affect the efficiency of the generator. The different efficiency in each workload will have an effect on the amount of heat rate production produced when compared. By calculating the efficiency at each load, it will be useful to find out the workload with the best performance. From the results of the enthalpy calculation process based on the temperature of each gas turbine process, in this study the gas turbine performance is calculated, and then it compares the turbine performance with variations in operating load. The turbine performance that will be calculated includes compressor power, turbine power, net power, thermal efficiency, compressor efficiency, combustion chamber efficiency, turbine efficiency, heat input, and heat rate. The results of the calculation of the highest average thermal efficiency at 27 MW load were 35.18%; the average compressor efficiency experienced the highest increase at 25 MW load of 83.24%, followed by an average increase in combustion chamber efficiency and an average decrease in turbine efficiency at each increase in load, as well as experiencing the lowest decrease in heat rate at 27 MW load conditions of 2,842 kJ/kWh
