6 FAQs about [Step up transformer for solar power plant]
How to choose a step-up transformer in a PV plant?
In general, the selection of the step-up transformer in a PV plant is a quite complex task as several variables depending on the transformer rated power must be taken into account as: initial cost of the system, energy losses due to transformer efficiency, energy storage system efficiency and possible plant disconnections due to grid instability.
What is a step-up transformer in a PV system?
Conventional distribution transformers are widely used, either singly or paralleled, to connect the inverter to the main power line. The step-up transformer is a key element of a PV system, as it processes the whole generated energy.
What is recommended for a solar power plant's step-up transformer?
For a solar power plant, it is recommended to use the in-situ step-up transformer without the excitation voltage regulator transformer.
Do step-up transformers cause grid instabilities?
Abstract: - Step-up transformers are used to connect large PV plants to the utility network, their sizing being often accomplished only taking into account the PV plant peak power. However, a largely unpredictable power injection on the main grid is obtained if a too large rated power is selected, leading to grid instabilities.
How to choose the rated power of a step-up transformer?
The selection of the rated power of the step-up transformer becomes more complex when considering a PV plant with energy storage capabilities, as an optimal solution must be detected taking also into account the features and the cost of the Energy Storage System (ESS) and their effects on the cost and efficiency of the whole system.
What is the voltage stepped up to by the solar step-up transformer?
The solar step-up transformer is used to step up the voltage to 10 kV or 35 kV in situ and is finally fed into the transmission and distribution system to complete the grid connection. The output voltage of the inverters is mainly 270, 315 and 400 V.
