Abstract

The performance evaluation of an in-pipe hydropower system with vertical axis parallel turbines prototype in a pipeline has been investigated in order to generate renewable energy. This is because the excess pressure, kinetic energy, and potential energy in flowing water can be used to generate electricity when water is used rather than wasted. Therefore, this study led to the development of a new design of an in-pipe hydropower prototype called prototype 40 (P40). This prototype is designed by dividing the water flow into two parts, namely the main water channel and the power generation (PG) channel. The PG channel contains a turbine on the side of the pipe. The flow of water in the PG channel is controlled by valves located in the inlet and outlet channels. If service and maintenance work needs to be done, the valves on the PG line can be closed to stop the water flow. This will not affect the water flow on the main channel as the water flow works normally. With the division of this water flow, it will not interfere with the water supply to consumers, which has become the main concern for water suppliers. An experiment was conducted on a laboratory scale to determine the increased power and efficiency of the prototype. The proposed method includes theoretical design, building a prototype, testing its performance, and analysing the data that was collected. Based on the findings, the prototype has worked according to the intended design. It allows most of the water to flow while using some of the water pressure for power generation. Therefore, the prototypes should be recommended for real-world implementation towards Technology Readiness Level (TRLs) 6 or higher.
