power is almost zero during a change in module temperature condition. This 40 MW solar PV plant is operated at its maximum power output to the grid with a solar irradiance level of 1000 W/m2 and module temperature of 25°C in OPAL-RT real-time simulator environment.
A large-scale PV plant consists [1, 3] of mainly of several thousands of PV modules (which converts solar energy into electric DC power) connected in series and parallel combinations to obtain desired voltage and power level. Solar inverters are the heart of solar PV plant that convert PV array generated DC power into low voltage AC power.
In a large-scale solar PV plant, it is normal practice to connect PCU output to a conventional converter duty multi-winding step-up PCU transformer to convert the low voltage DC power output of the PV array into MV AC grid with galvanic isolation.
The design and modelling of a grid-connected 40 MW (AC) solar PV plant have been carried out with SHE modulated 11L-CHB VSC and a 12-pulse configuration of the transformer. Test results using real-time OPAL-RT simulator technologies are presented.
Solar inverters are the heart of solar PV plant that convert PV array generated DC power into low voltage AC power. The medium voltage (MV) transformers (6.6– 33 kV range) are used to step up the low solar inverter output voltage up to a voltage level required for AC grid integration.
The solar PV plant grid current THD value is 0.96% (33 kV level), which is well within the acceptable limit defined in the IEEE-519 standard .
