Application of water supply operation system to improve efficiency of hydraulic power generation

摘要

At various locations in Tokyo, the excess pressure of water entering the water supply distribution reservoirs is adjusted by pressure reducing valves, wasting unused energy. The installation of hydraulic power generation equipment is now promoted in place of the pressure reducing valves. This is a renewable energy source as the method produces no greenhouse gases and reduces fossil fuel use. The results of research into the operation of the hydraulic power generation equipment enable the water supply operating system to optimize the inflow rate for power generation without affecting the stability of the water supply. This has increased the amount of power generated and enabled earlier recovery of total costs.
