Abstract

In Musi Hydropower Heat Exchanger is used to cool the generator. As we know, the generator is a vital component in a generation electricity wire. The function of the generator is converting mechanical energy from the turbine into electrical energy. Generators in everyday use require cooling in order to extend service life. Due to extremely high operating temperatures can cause damage to the generator components. The importance of the effectiveness of the heat exchanger is happening is to look at the performance of the ground heat exchanger. Data obtained as inlet and outlet water temperature (Tc,in and Tc,out), oil temperature log (Th,in and Th,out) and the flow of water and oil flow capacity (Qc and Qh) is used to calculate the effectiveness of the heat exchanger . In calculating the heat exchanger effectiveness, there is some value to look like Density (ρ), specific heat (Cp), the mass flow rate ( ṁ c and ṁ h), the real heat transfer (Q), the maximum possible heat transfer (Qmax), the coefficient heat transfer to the water and oil (Cc and Ch) and the last search effectiveness (ε). The results of calculation of heat exchanger effectiveness is happening at unit 1 Musi Hydropower of Ujan Mas Kepahiang, can be considered to be ineffective and inefficient, as heat exchangers work effectively under state or in other words the heat exchanger is not working properly in accordance with the (far from the boundaries of normal). This is because the maintenance and repair of heat exchangers made far from perfect.
