Title:
SYSTEM THAT INTERLINKS WITH HYDROELECTRIC POWER GENERATION LINE
Document Type and Number:
WIPO Patent Application WO/2019/208728
Kind Code:
A1
Abstract:
Provided is a system that links with a hydroelectric power generation line, wherein general-purpose components can be used for functional units designed for line interconnections, and costs can be reduced while ensuring quality. The invention comprises a water turbine (1), a generator (3) that converts rotational energy of the water turbine to electrical energy, a rectifier (15) that converts the power generated by this generator (3) to DC power, a power conditioner (8) that converts the DC power rectified by this rectifier (15) to AC power that can be interconnected with a line (9), and a control device (4) that adjusts the load of the generator (3) and controls the rotational speed of the water turbine (1). The power conditioner (8) is an integrated general-purpose component and is, for example, a power conditioner for solar power generation.
