It will be find that there is a strong group in ASKON, providing comprehensive solutions and services for advanced marine propulsion system. With long-term experience in the field of marine propulsion and the latest management innovations, AKSON launch propulsion power system with superior performance and high-reliability. A lot of lifting equipment, which would be result in a huge impact on the ship's power supply system, are used on large ships,
Scheme of Harmonic governance
Based on the estimated distribution system load capacity of various types, taking into account the parameters of the project index requirements, AKSON recommend the user adoption AKSON’s active filter which have the following functions:
■ Automatically adjusting the output based on changes in the way of grid operation and load fluctuations, in order to offset the harmonics in the grid.
■ Independent of the grid impedance and system impedance, not be affected from the grid impedance and impedance change.
■ Harmonic of 2-50 times and at least 15 kinds of harmonics can also be filtered out. All the harmonics are provided with a control unit respectively. Each harmonic paragraph can be set according to user needs and target value can be set for the harmonic filter separately.
■ Filtering and reactive power compensation can be set by the user’s requirement meanwhile.
■ When filtering , compensation is completely avoid.
■ The active filter have completely protection device, which including overload, over current, short circuit, over (under) voltage, voltage unbalance, phase sequence protection, frequency, ground fault, IGBT over temperature protection. It also has a system of self-diagnosis function, which can indicate the cause of the malfunction when a fault is detected,.
■ With remote communication interface for access control system, which can meet the requirements of the monitoring function of rail transit power supply system.
■ With man-machine interface with a liquid crystal display and operation keys, which have parameter settings, the status change, information and other operations. And the interface can also indicate the operating conditions, the measurement data, fault alarm.
■ With the high frequency filtering circuit, which can filter out high frequency carrier from high frequency switching of the IGBT itself. The circuit ensures that the carrier does not back to the grid, which can cause interference to other systems and devices.Since the electronic pusher has a great deal of flexibility, efficiency and superior performance.They are widely used in the ship propulsion of today's technology.
AKSON provides the control system for propulsion systems of ships and floating platforms and auxiliary applications.
