The working principle of a turnkey station with an integrated MV transformer?
High-Voltage Incoming Line
Receiving Electrical Energy: High-voltage transmission lines deliver electrical energy to the high-voltage side of the turnkey station.
Protection and Control: High-voltage circuit breakers and disconnect switches are used to control the on-off of electrical energy, and lightning arresters are used to protect the equipment from lightning strikes and overvoltages.
Medium-Voltage Transformer
Voltage Conversion: The medium-voltage transformer converts high-voltage electrical energy (such as 110 kV, 35 kV) into medium-voltage electrical energy (such as 10 kV, 20 kV).
Cooling System: The transformer generates heat during operation, and the cooling system (such as oil cooling, air cooling) ensures that the transformer operates within a safe temperature range.
Protection Devices: The transformer is equipped with various protection devices, such as overload protection, short-circuit protection, temperature protection, etc., to ensure the safe operation of the transformer.
Medium-Voltage Outgoing Line
Electrical Energy Distribution: Medium-voltage electrical energy is distributed to end users or the next-level distribution system through medium-voltage circuit breakers and disconnect switches.
Protection and Control: Medium-voltage circuit breakers are used to control the on-off of electrical energy, and disconnect switches are used for safe isolation during maintenance.
Control and Protection System
Monitoring: Relay protection devices and SCADA systems monitor the running state of the system in real time, including parameters such as voltage, current, and temperature.
Protection: Relay protection devices quickly cut off the power supply when detecting abnormal situations (such as short-circuit, overload, overvoltage), protecting the safety of equipment and personnel.
Automation Control: PLC controllers achieve automation control, automatically adjusting the running state of the system according to preset logic and parameters.
Auxiliary Systems
Cooling System: Ensure the normal operation of transformers and other equipment in a high-temperature environment.
Ventilation System: Provide a good ventilation environment to prevent equipment from overheating.
Lighting System: Provide sufficient lighting to facilitate operation and maintenance.
Security System: Include video surveillance, intrusion alarm, etc., to ensure the safety of the station.
