Abstract

The invention relates to a control device of a throttle device in a ship electric propulsion system, in particular to an electric propulsion ship converter control unit, which comprises a control power supply board, a communication board, an analog quantity board, a digital quantity input and output board, a DSP (Digital Signal Processor) main control board, a pulse transmission board, a state feedback board, a power module power supply board and a mother board, wherein the mother board is connected with one end of each of other eight circuit boards through a connector; panels are respectively arranged on the other ends of the eight circuit boards; part of the eight circuit boards is connected with an external low voltage electric port through a 48-chip connector; an optical fiber board is connected with a drive and fault feedback signal of a power module through optical fiber; data (such as torque, frequency, current, voltage, running signals, fault signals, fault type, gears feedback and other signals) transmission is realized by adopting a PROFIBUS communication mode. The electric propulsion ship converter control unit is applicable to control and protection of electric propulsion ships.

Description

technical field [0001] The invention relates to a control device for a throttle in a ship electric propulsion system, in particular to a control unit for a converter of an electric propulsion ship. Background technique [0002] At present, the main propulsion system of traditional ships generally adopts the mechanical propulsion method of diesel engine + gearbox + propeller. It has obvious advantages in terms of ship manipulation, layout, safety and reliability; the converter in the electric propulsion system is used as a power conversion component, which plays a role in connecting the preceding and the following. The converter receives the constant-voltage and constant-frequency alternating current from the diesel The constant frequency alternating current is converted into variable voltage and variable frequency alternating current and sent to the propulsion motor, and the propulsion motor then drives the propeller through the gearbox to realize the forward, backward, trac...
