REFERENTIAL PHOTOVOLTAIC ELECTRIC POWER STATION

The brief description of the solution:

• Manufacture of electric energy is realized by means of 1,170 Suntech photovoltaic panels, type STP 180S-24/Ad, with power of 180 Wp, installed by reason of increasing the overall production on 43 single-axis stands of own design (tracks) with an automatic sun-movement tracking system. The stands are equipped with a central control system – PLC Mitsubishi, which, together with exposition sensors, provides optimal rotation of the panels in the direction of the sun. Conversion from DC to AC is solved by a corresponding number of inverters, type SMC 8000 Tl ESS, in a decentralized configuration. A non-positionable fixed stand with 52 panels and one inverter, type SMC 8000 Tl ESS, serving for the comparison of production, is installed in the electric power station.
• The electric power station is connected to the distributing network via a withdrawn-energy measurement system and distribution substation
• The control system of the electric power station enables remote inspection, visualization, tracking and archiving of the operational data, as well as tracking and archiving of possible alarm states.
• The entire facility of the electric power station is fenced and equipped with a basic safety and camera system.
• It is supposed that the electric power station should be operated year-round and automatically.
• The proposed service life is 30 years.
