Medium Voltage
Enhancing Power Quality with Medium Voltage Inverters
Medium voltage inverters are one of the most popular types of inverters used. It is necessary to utilize a medium-voltage inverter for units that employ machinery with medium-voltage motors that have a voltage range of 1kV to 66kV.
Increasing demand for energy efficiency drives market growth. In addition, according to a research report by Astute Analytica, the United States medium voltage (MV) inverters market is likely to increase at a compound annual growth rate (CAGR) of 5.7% over the projection period from 2023 to 2031.
How do medium voltage inverters work?
Power cells or miniature inverters convert low-voltage alternating current into the necessary frequency of alternating current in the medium-voltage inverter. Power cells are managed by optical signal, which ensures synchronization. The appropriate output voltage is produced by connecting power cells in series or cascading them together.
People were able to comprehend the fundamental ideas behind the construction and operation of a medium-voltage inverter. It is crucial to choose a high-quality inverter at an affordable price because they have a relatively high investment cost.
How is a medium voltage inverter built?
The medium voltage inverter's structure will vary depending on the capacity and use need, but it will always consist of the following essential parts:
Transformer cabinet: The purpose of the transformer cabinet is to supply power cells and reduce the source voltage to the proper level.
Control cabinet: The communication module and PLC are included in the control cabinet, which can calculate and communicate with power cells.
Power cells: Depending on voltage and capacity, each phase can have from 3 to 8 power cells or more.
How many kinds of medium voltage inverters are present?
The medium voltage inverter can be divided into the following types based on its installation space and capacity:
Separated: The dimensions of this inverter are just right. It has a reasonable capacity. This inverter has good cooling capabilities.
Compact: It's a compact inverter designed specifically for small spaces.
Water cooled: This series of inverters requires water cooling to maintain equipment longevity and productivity because their current ratings exceed 800A.
Purposes of medium voltage inverter
Using an inverter (such as a medium voltage inverter) might reduce the amount of massive additional power generation equipment needed to satisfy peak power usage periods and postpone investments in grid expansion.
In general, distributed solar power plants must be installed at locations where electricity is consumed, such as cities. Photovoltaic modules can also serve as a vehicle for popularising and teaching the public about photovoltaics. In addition, it raises public awareness of environmental issues and encourages the use of renewable energy.
Distributed energy sources will affect the distribution system widely and extensively. They are typically connected to low- or medium-voltage distribution networks. From a technological perspective, the inverter is essential for managing the reciprocal influence between dispersed solar power plants and the grid throughout their integration.
An inverter with a medium voltage is required for some processes. The solar inverter is the key to unlocking the potential of distributed photovoltaic power plants by facilitating their better integration with the local grid system.
