Shore power inverter with since the generation and application background of reform and opening up, China's shipbuilding industry has developed rapidly, China has become the world's largest shipbuilding country. More and more countries and regions, in our shipyard custom-made in line with its standards and frequency, voltage requirements of various ships, and maintenance of various ships. during shipbuilding, ship a lot of equipment are required for proper use 60Hz power supply due to the power grid of the power frequency standard 50Hz, generator on board in the absence of normal Before put into use, these need to 60Hz power supply equipment, access to China's power grid use is not working.

Power supply repair shipbuilding past traditional way: by a three-phase 380V / 50Hz motors (synchronous or asynchronous) led 440V / 60Hz generator power to the board, the shortcomings are more noise, and low efficiency; failure rate, convenient maintenance must be managed by hand, when sudden heavy load output voltage difference of dynamic characteristics, frequency instability, to repair shipbuilding industry as a professional power equipment - static Marine Shore Power, came into being, because of its 50Hz into 60Hz power capabilities, more cost-effective, can be provided to different standards of ship shore power; compared with the generator, saving more than 20 percent, eliminating the need for a generator to bring more noise, high operating costs, loss large, there is pollution, maintenance difficulties, someone must manage many other inconveniences; the function has more applicability, advantages of real-time monitoring of the operation of the power supply, etc., widely used by major domestic shipbuilding, ship repair companies.

Compared Shore Power generator features:

1, the voltage source, the direct three-phase 380V / 50Hz input, output stable phase 450V / 60Hz power supply.

2, less current harmonics, no harmonic suppression device.

3, the output sine wave, a wide range of input voltage for output voltage and frequency fluctuation is small, complete common parameter setting functions.

4, efficiency) of 90%, compared with conventional inverter generator set more than 20% energy saving.

5, saving manpower: easy to operate, no special duty management.

6. Easy maintenance: installation, configuration, debugging simple.

7, use of safety: Powerful protection, overcurrent, overvoltage, overload, short circuit, lack of equal protection.

8. Cost savings: See application examples.

9; by shore power supply applications; ship repair can greatly shorten delivery time: see application examples.

Cost Analysis of a ship repair company Shanghai to install shore power supply after

The company uses a three-phase 380V / 60Hz power supply, power production 24 hours a day. The existing generating normal for 100kW, far from meeting the needs of ships. Peak line current is 140A, once all produce more than 50 mA current (RMS), I plant to generate electricity using a 300kW generator for the production of equipment; when the power supply; obviously feel more difficult generator; and the output frequency range ± l cycle; the output voltage fluctuation range of about 15V ( including the main line loss), the output voltage total harmonic distortion THDu = 2.4% (full load).

Now in use shore power supply, using a common part of the drive as an inverter; use special design to output isolation dry type transformer regulating transformers; use SIN2500A sinusoidal filters; all the air out of the output switch intelligent switch allows selection of test power output voltage total harmonic distortion at no load THDu = 0.8%; full load THDu = 1.8%; no-load output voltage fluctuation is less than 3.8V; Load current 0 ~ 190A sudden change in voltage fluctuation is less than 7.4V; output frequency is always stable at 60Hz. The power quality is better than the generators, the plant production equipment to fully meet the requirements for power use shore power supply not only provide better quality than the generator power supply, and more have very objective economic After using 600kVA inverter power supply, the plant average monthly energy cost savings of 86,039.08 yuan (Note: taking into account the factors that generate electricity and months in April due to power outages and electricity for their own use; if you do not consider the above factors; the average monthly savings Energy costs amounted to more than 100,000 yuan). The calculated static frequency power supply equipment investment recovery period is 5.6 months, showing that its economic benefits are very impressive.
