Photovoltaic power generation



With introduction of fixed price wholesale purchase system for renewable energy, PV system-related market expands rapidly, and growth of market will be expected in future.
We make use of technique and knowledge that we cultivated in electricity apparatus including transformer and sell power conditioner, various system connection facilities, voltage regulators (SVC). Our technique takes part of the spread of photovoltaic power generation.

[facilities of schools line]

Electricity which generated electricity with solar cell sells electricity by fixed price wholesale purchase system to electric power company. Conversion (up-convert) system ream system facilities to do are necessary for high pressure with electricity that generated electricity on this occasion to play consecutive system to commercial power supply (system) of electric power company.



Less than 50kW - 2,000kW  High pressure facilities  Transformer for voltage up, high platen, switchboard in place
2,000kW or more  Special high pressure facilities  Transformer for voltage up, high platen, switchboard in place, special serviceman monitoring board

[voltage regulator]

The voltage adjustment apparatus which adds to importance by the spread of photovoltaic power generation

Because quantity of generation changes under the influence of the neighboring situation such as weather or season, as for the photovoltaic power generation, the voltage of power line connected by the sudden increase and decrease of quantity of generation might largely fluctuate. Therefore electric power company managing power line may demand adjustment of reactive power and power factor from photovoltaic power generation company. As our SVC can control rise in power line voltage by coordinating reactive power, we are introduced a lot into photovoltaic power generation facilities.
