Photovoltaic and new energy systems depends on the electrical equipment functioning under various voltage, loading and grid conditions. As PV systems, energy storage systems, and other electrical equipment are installed in different countries, issues of voltage compatibility, electrical isolation and power stability should be addressed.
Industrial type transformers, voltage stabilizers and frequency adjustable Power supplies may be used to meter various power adapting for PV and new energy applications ranging from voltage conversion and isolation.
The photovoltaic and energy storage projects frequently need multiple Electrical devices such as inverters, transformers, distribution equipment, energy storage systems, monitor systems, industrial control equipment, etc.
Each component has its own electrical requirement. From this the electrical power sources have to be matched appropriately to the voltage and frequency, phase and capacity requirements of the equipment.
Furthermore, PV and other new energy equipment may be installed in a market with a different electrical norm. A system is designed for one voltage or frequency using various power equipment may need more power equipment when exported to another market.
By using a correctly chosen transformer, voltage stabiliser, or variable frequency power supply, these electrical adaptation needs can be satisfied.
The different electrical systems and different countries have different levels of voltage. Equipment to be connected in photovoltaic cell, energy accumulator or manufacturing plant should maybe need to be transformed before be connected to the electrical system.
The industrial transformers can be used for step-up or step-down conversion of voltage, depending on the requirements of the system.
Voltage on the grid may vary due to changing loads, long distribution feeders, switching operations or other electrical conditions.
May require power supply of a more stable nature: control systems, monitoring equipment, electric mechanisms.
Industrial voltage stabilizers regulate voltage within a given band, which allows the machinery to work in a more stable environment.
Certain applications may also necessitate electrical isolation of the power electronics and control sections of photovoltaic and energy storage systems.
It is an isolating transformer between the primary and secondary circuit with the voltage transformation of the required value. This is beneficial in applications where electrical isolation and power-quality processes are involved.
More and more equipment being made and used around the world with new energy. Gear designed for system 380V/50Hz, could be installed or tested using 480 V/60Hz.
A typical transformer may step voltages up/down, however in most cases it will not change the supply frequency. If both voltage and frequency need to be controlled then a variable frequency power supply will be needed.
Isolation transformers provide electrical separation between the input and output circuits while allowing voltage conversion when required.
For PV and energy storage applications, isolation transformers can be considered where the system requires:
The actual transformer design should be selected according to the inverter characteristics, system voltage, load capacity, grounding arrangement, and project requirements.
Stable voltage is important for many electronic and electrical components used in photovoltaic and new energy systems.
When the incoming grid voltage varies beyond the acceptable operating range of the equipment, an industrial voltage stabilizer can regulate the output voltage to provide a more stable supply.
Potential applications include:
Voltage stabilization can be particularly useful in industrial facilities where multiple high-power loads operate simultaneously and affect the local power supply.
Variable frequency power supplies provide controlled voltage and frequency for equipment testing and specialized power applications.
In the new energy industry, they can be used for testing equipment that needs to operate under different electrical conditions. This is especially relevant for manufacturers and laboratories developing or testing inverters, power conversion equipment, and other electrical products.
Typical applications include:
For manufacturers serving multiple international markets, adjustable voltage and frequency can make it easier to reproduce different grid conditions during product testing.
