Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] The invention is an adjustable frequency and voltage device capable of simulating ship generators of different frequencies.

[0016] Such as figure 1 As shown, the simulated ship generator device of the present invention is to output the 380V power supply through the power conversion device to meet the requirements of the three-phase power supply of 40V / 60Hz or 400V / 50Hz according to the frequency modulation and voltage regulation signals, and provide it to the shore power connection equipment. Instead of the real on-board generator, carry out the detection of shore power equipment.

[0017] Such as figure 2 As shown, the simulated marine generator device of the present invention includes an incoming line AC contactor 1, a rectification and filtering circuit 2, a frequency conversion and voltage conversion system 3, an outgoing line A...

Abstract

The invention discloses a ship electric generator simulating device which comprises a wire inlet alternating current contactor, a rectification filter circuit, a frequency conversion and voltage transformation system, a wire outlet alternating current contactor, a master control system, a driving and protective circuit, a liquid crystal touch screen and a PLC. The wire inlet alternating current contactor is connected with the input end of the rectification filter circuit, the output end of the rectification filter circuit is connected with the input end of the frequency conversion and voltage transformation system, the output end of the frequency conversion and voltage transformation system is connected with the wire outlet alternating current contactor, the PLC is respectively connected with the master control system and the liquid crystal touch screen, the master control system is respectively connected with the driving and protective circuit and the liquid crystal touch screen, the driving and protective circuit is connected with the frequency conversion and voltage transformation system, and electrical parameter signals at the output end of the frequency conversion and voltage transformation system are input into the master control system. A shipborne electric generator is replaced by the ship electric generator simulating device to carry out testing, and small signals are simulated to be large currents in actual working conditions to carry out detection on shore power devices.

Description

technical field [0001] The invention relates to a simulated ship generator device, which belongs to the technical field of ship electrical equipment. Background technique [0002] With the rapid growth of global shipping business, the environmental pollution caused by marine transportation is becoming more and more serious. Since almost all ships in the world use generators that burn light or heavy diesel to generate electricity by themselves, each ship is equivalent to a small power generator. factory, a mobile chimney, which not only causes pollution, but also wastes energy. Compared with the power generation of the ship's auxiliary engine, the ship in port can turn off the auxiliary engine after receiving shore power. The shipowner can save fuel costs and reduce emissions and noise. Due to the good environmental protection and economy of shore power projects, more and more ships use shore power. The shore power control panel is the control center connecting the ship and...
