ATS Control

The generator ATS cabinet is a control cabinet for automatic transfer switchgear, which is used to realize automatic switching between diesel generator sets and mains power, ensuring that critical loads can continue to operate stably when power is interrupted. 1.composition： Control components and circuit breakers: ATS automatic switching cabinet consists of control components and circuit breakers, which can be manually or automatically controlled to switch on and off for power supply. PC-level and CB-level switch bodies: Switch bodies are divided into PC-level (integrated type) and CB-level (circuit breaker type). PC-level has a simple structure, small size, and fast switching function, but needs to be equipped with a short-circuit protection device; while CB-level is equipped with an overcurrent release and has a short-circuit protection function. Controller: The controller detects the working status of the monitored power supply and issues action instructions when a fault occurs to achieve automatic power switching. 2.Function： Fully automatic switching: ATS cabinet can realize fully automatic switching between mains power and generator sets, ensuring the continuity and reliability of power supply. Delay function: The system has a variety of delay functions, including mains power recovery delay, mains power failure confirmation delay, etc., to ensure the stability of the power supply system. Remote control, telemetry and telesignaling: Modern ATS cabinets can realize the remote control, telemetry and telesignaling functions of dual power supply switching, improving the convenience and accuracy of operation. 3.Applications： Important power-consuming places: ATS cabinets are particularly important in places with strict requirements on power supply, such as hospitals, data centers, industrial production lines, etc., to avoid losses caused by power outages. Unattended operation: ATS cabinet can realize unattended operation, automatically handle power switching, and reduce manual intervention and maintenance costs.   The generator ATS cabinet provides reliable power protection for key facilities through its advanced automatic control system and multiple protection mechanisms. When selecting and using the ATS cabinet, our company will fully consider its technical parameters, performance characteristics and maintenance requirements to ensure the efficient operation of the power system.

WHAT DOES A GENERATOR CONTROL PANEL DO? The generator control panel can essentially be seen as the user interface that allows operators to control the generator, as well as check on system diagnostics, overall functions, and current status of a generator. Generators are heavy pieces of machinery and like all heavy equipment, can be prone to overheating, fluctuations in speed, and can suffer from everyday wear & tear, engine fatigue, or be affected by ambient temperatures and climate. Critical functions include protecting your generator’s engine by monitoring oil pressure, coolant temperature, and automatically shutdown the generator engine to prevent irreparable or costly damage. HOW DOES A GENERATOR CONTROL PANEL WORK? Generator control panels contain a microprocessor that can process and manipulate input from sensors to help provide feedback to the genset to monitor itself and manage any processes that come about. A common feedback setting would be temperature. When the generator engine begins to reach temperatures meet or exceed to temperature sensor setting, the generator could be prompted to shutdown automatically to prevent damage. Generator control panels are often paired together with an Automatic Transfer Switch (ATS). An ATS will prompt the generator to kick in seconds within the event of power loss due to power outage. Once power is restored from the main power grid, the generator will be prompted to shut off, as service from the main grid will resume. This is simply due to the fact that because the ATS is connected to the main grid, the ATS can detect an outage and signal the control panel to start the generator without the need to manually start the generator. Without an ATS (Automatic Transfer Switch), you will need staff on-site to manually flip the switch on the generator controls to run the generator in the event of a power outage and must also manually turn off the generator once power is restored. Failure to turn off the generator after power to the main grid is restored can cause an effect called back feeding, which can be lethal to any electricians that are working on the power lines. POTENTIAL BENEFITS OF GENERATOR CONTROL PANELS Generator control panels offer a variety of benefits, including： Error elimination: A generator control panel helps eliminate operating errors. Increased efficiency: Improved generator control can help your generator run more efficiently. Improved safety: Current and volt supervision support safer operation. Fewer costs: Enhanced generator control will help lower generator upgrade frequency as well as maintenance and operation costs. Enhanced reliability: Being able to monitor generator function and perform event analysis can yield insight on making your generator more reliable.

Traditional ATS systems switch loads from main power to generators during power outages. Even a 10 millisecond power outage can cause server crashes, data corruption, or industrial machinery to stop. Integrate Eaton UPS into ATS cabinets to create an "uninterruptible" power bridge.   Adding Eaton UPS (uninterruptible power supply) to ATS cabinets has the following main functions:   Provide uninterruptible power supply: When the mains power fails, voltage fluctuates, frequency is abnormal, etc., Eaton UPS can switch to battery power mode in a very short time (such as some Eaton UPS can be within 4 milliseconds), ensuring that load equipment will not stop working due to mains power outages and ensuring business continuity. For example, in places such as data centers and hospitals, even short power outages can have serious consequences, and UPS can prevent this from happening.   Improve power quality: Eaton UPS has a high-precision voltage stabilization function. For example, the output voltage accuracy of Eaton 9SX series can be controlled within ±1%, and the frequency accuracy can be controlled within ±0.1Hz. It can also reduce the harmonic distortion rate of the output current through technologies such as built-in harmonic filters, provide pure and stable power for load equipment, and reduce the damage to equipment caused by power anomalies. For some precision instruments and electronic equipment that have high requirements for power quality, it can effectively avoid failures or damage caused by voltage instability, harmonics and other problems.   Enhance system reliability: UPS cooperates with ATS. When one power supply fails, ATS automatically switches to another power supply. If the other power supply also has problems, UPS can continue to supply power as a backup power supply, forming multiple guarantees. At the same time, Eaton UPS itself has high reliability, adopts advanced design and manufacturing technology, and some series also support redundant parallel function, which further improves the reliability of the entire power supply system.   Why add UPS to ATS cabinet? 1. Fill the ATS switching gap When ATS switches the main power supply (such as mains → generator), there is usually a millisecond power outage, and UPS can supply power through the battery at the moment of power outage to eliminate this gap and ensure the continuous operation of the load. 2. Dual redundancy protection ATS is responsible for the automatic switching of the main and backup power supplies, and UPS is responsible for uninterrupted power supply in a short period of time. The combination of the two forms a dual protection of "power switching + energy storage buffer" to avoid load interruption caused by switching delays or failure to start the backup power supply. 3. Optimize power quality UPS can filter voltage fluctuations, harmonics and other interferences in the power grid to provide stable power supply for the load, while ATS mainly solves the problem of power outages. The two functions complement each other. Adding UPS to the ATS cabinet is an effective means to improve power supply reliability. The core lies in eliminating power outage gaps and optimizing power quality through the dual mechanism of "power switching + energy storage buffer".
