Diesel generator ATS control cabinet dual power conversion system
Description
Diesel generator ATS is an "automatic switching system", which is a device (cabinet) that controls the switching between the mains power and the generator. It is powered by the mains power during normal operation, and automatically or manually switches to the generator power supply after the mains power is interrupted! The usual and simple method is to use a rotary switch to select automatic, manual, or remote control unit communication devices.
The ATS cabinet is suitable for a variety of power systems, especially places with strict requirements for power outages, such as hospitals, data centers, financial institutions, etc. In these places, the stability of power supply is crucial to ensure normal operation. The ATS cabinet can realize the unattended function. When the mains power returns to normal, it will automatically switch back to the mains power supply and delay the stop of the generator set, thereby achieving rapid recovery of the power supply system.
What does ATS mean in diesel generator sets?
The ATS cabinet is mainly composed of an intelligent controller and a high-performance dual-power automatic switching switch. When the mains power is out or a fault occurs (such as phase loss, undervoltage, loss of voltage or frequency deviation, etc.), the ATS cabinet can automatically detect and issue an action command to enable the switch body to quickly switch from one power supply to another to ensure continuous and reliable operation of important loads.
The panel displays the voltage and current of the two power supplies. Frequency, power and other electrical quantities, and also displays the power supply status of the two power supplies. Through the control module setting, it can be set on site to one power supply priority, two power supplies priority or no priority (i.e., mutual backup) power supply mode.
What is the working principle of ATS cabinet?
By monitoring the main power status, it detects failures and automatically switches to the backup power source when necessary.
• Monitoring the main power supply: The ATS cabinet monitors the voltage, frequency, phase sequence and other parameters of the main power supply in real time through built-in sensors. When the main power supply is normal, the ATS cabinet remains in the main power supply state, the motor does not work, and the switching device remains in the main power supply position.
• Detecting faults: Once the main power supply is out of power or fails (such as phase loss, undervoltage, loss of voltage or frequency deviation, etc.), the ATS cabinet will immediately detect these abnormal conditions.
• Switching power supply: According to the set logical rules, the controller of the ATS cabinet will issue an action command to quickly switch the switching device from the main power supply to the backup power supply. This process is usually completed within a few milliseconds to a few seconds to ensure the continuous and reliable operation of important loads.
• Restoring the main power supply: When the main power supply returns to normal, the ATS cabinet will perform corresponding operations, disconnect the backup power supply, and reconnect the main power supply
