Electric wind power unitized substation Introduction

 Use in Harsh Environments
Due to the specific nature of wind farm environments, wind farms are often seen in regions with strong winds, such as the Northwest and Northeast, as well as coastal areas with sufficient wind power for electricity generation. Additionally, wind farms can be found in places with heavy salt spray. These natural conditions in these areas are quite harsh, so it is essential for personnel to pay attention to the protection of the electric wind power unitized substation’ enclosures when used in these regions. Furthermore, the switches inside the transformer play an extremely important role in the subsequent operation of the transformer. Therefore, personnel need to apply advanced materials for corrosion resistance, freeze resistance, exposure protection, and salt spray resistance to these switches in advance to ensure the integrity and accuracy of the switches during the transformer’s operation.

 Prolonged Low Load Operation
Under the influence of the working environment in wind farms, transformers often operate in a state of low load. Additionally, seasonal changes can also affect wind power, resulting in variations in the working conditions of wind power generation due to seasonal changes. Generally, most transformers have an average annual load rate of around 30%, which is the primary reason for prolonged no-load operation of transformers. The no-load operation of transformers also incurs certain losses, so personnel strictly control the losses during the no-load operation of these transformers. To enable wind turbines to have self-diagnostic capabilities during operation, wind turbines typically employ microcomputer control. This means that when a wind turbine experiences an overload situation during operation, it will be subject to speed limitations or mandatory shutdown under the influence of microcomputer control. Transformer capacity is generally greater than that of wind turbines, so transformers do not experience overloads during operation, and thus, there is no need to consider overloading of transformers.

 Careful Component Selection
Wind power generation devices are inevitably prone to accidents. To minimize the impact of such occurrences on the power grid, appropriate high-voltage load switches should be installed on the 35kV electric wind power unitized substation. This allows for the timely shutdown of the power source in case of overload in the transformers. The weather in nature is ever-changing, so to prevent the damaging effects of high voltage on transformers caused by high voltage in wind power stations, lightning protection devices should be installed.
