Conditioning Mode:

During the conditioning mode, when the mains supply operates within the defined tolerance range, the synchronous machine assumes the role of a motor. This facilitates the driving of the main shaft and, consequently, the accumulation of kinetic energy within the system. As the inner rotor achieves a rotation of 1500 rpm (50Hz), the outer rotor responds by reaching a maximum speed of 3000 rpm. The outcome of this process is the efficient storage of kinetic energy.

Independent Mode:

In the independent mode, activated in scenarios such as mains failure or voltage disturbances, the kinetic energy stored within the system undergoes a seamless transfer to the state-alternator, which takes on the role of a generator. This transition transpires without causing any disruption to the user experience. Subsequently, the diesel engine initiates its operation, engaging with the state alternator via an electromagnetic clutch. Energy transmission follows suit, progressing from the diesel engine to the synchronous machine and finally to the connected loads.

Sequence:

• QD1 Opens
• The kinetic energy harnessed from the outer rotor plays a pivotal role in maintaining the frequency at 50 Hz, held within a tight tolerance of +/- 1%.
• The engine begins its operation.
• The electromagnetic clutch closes.
• Upon the engine attaining a rotational speed of 1500 rpm, power transfer to the loads commences and persists until the mains supply is restored.

Transfer from Conditioning Mode to Independent Mode:

Visualized in the accompanying graph, the transition from conditioning to independent mode is showcased and then reversed. Throughout this process, the frequency is meticulously maintained within narrow tolerances. The speed of the accumulator gradually decreases, subsequently triggering the initiation of the diesel engine to provide power to the connected load. Should an unforeseen failure occur during the diesel engine start-up, the electromechanical clutch promptly closes after the QD1 opening, thus harnessing the kinetic energy of the accumulator to commence the diesel engine. This redundancy establishes the NO-BREAK KS® as equipped with a dual-start capability, offering an additional guarantee for engine activation.

Mains Return: Back to Conditioning Mode:

Upon the restoration of the mains supply, the NO-BREAK KS® seamlessly synchronizes with it. The outer rotor swiftly re-accelerates to its designated speed. Upon achieving the rated kinetic energy storage, QD1 closes. The electromagnetic clutch disengages, thereby facilitating the closure of the clutch. Subsequently, the diesel engine operates at an idle speed, serving the purpose of cooling before eventually coming to a halt. This comprehensive system ensures that critical loads are safeguarded against an unlimited number of repeated mains failures.
