For international ships, the frequency of the ship's power supply equipment is generally 60Hz and the voltage level is generally 6.6KV or 460V, while for domestic ships, the frequency of the ship's power supply equipment is generally 50Hz and the voltage level is generally 6kV or 400V. To meet the requirements of national energy conservation and environmental protection, it is necessary to gradually stop the power supply of onboard diesel power generation systems and supply power to onboard auxiliary equipment through the onshore power supply. Considering that the frequency of the domestic power grid is 50Hz, it is impossible to directly supply power to the equipment on board. It is necessary to convert the 50Hz power supply onboard into the 60Hz power supply that can be used by the ship through the special shore power supply system onshore, and supply power to the ship through the junction box at the wharf apron, cable winch, etc.       According to the different types of ships, comprehensively consider the working conditions of the wharf. Our company can provide flexible and diverse high and low-voltage shore-based power supply solutions. Can be roughly divided into;1. High voltage ship shore power system2. Low voltage ship shore power system3. High and low voltage hybrid shore power system4. Large capacity multi-machine parallel shore power systemComposition of shore power system      The ashore power system can be divided into three parts: the shore power supply system, cable connection equipment, and ship power receiving system. Onshore power supply system: the onshore power supply system supplies power from the substation (substation) to the connection point close to the ship. Cable connection equipment: cables and equipment connecting shore connection points and shipboard power receiving devices. The cable connection equipment must meet the requirements of fast connection.      Ship power receiving system: the power receiving system is fixedly installed on the ship, which may include a cable winch, onboard transformer, and relevant electrical management system.Shore power system equipment supplyMain technical parametersContentParameters Remarks Input Rated input voltage 3-phase 6 / 10KV (- 35% ~ + 10%)  Rated input frequency 50HZ±3%  Fluctuating voltage The grid voltage drops within 35%, and the frequency converter operates with derating   power factor ≥ 0.96 (load greater than 20%) Output Rated output voltage 3-phase 6 / 6.6/10/11kv  Rated output current 100A~1160A  Output power range 1000≈20000KVA Basic performance Overload capacity 150% 1min 180% immediate protectionThe protection curve can be set Power system efficiency 97%  frequency resolution 0.01Hz  Total harmonic distortion (THD) Less than 3%Meet the national standard gb14549-93 and eee519-1992 power quality standardsControl interface display The multi-language color man-machine interface can simultaneously display basic electrical parameters such as input and output voltage, current and power, as well as real-time operation status, alarm recording, and event recording functions  set up Multi-function parameter setting  operation Local, remote control, and host computer communication Control Analog input / output 3-channel analog input, 4-channel analog star output voltage type, or current type can be set, and the input and output function can be set to 0 (4) ~ 20mA, 0 (2) ~ 10V, etc. ( 7 types can be selected )  Digital input / output 38 digital input functions such as 8-channel digital input and 5-channel digital output (expandable internal virtual REV/FWD) can be set, alarm barrier can be set, and 52 digital output functions can be set  Communication function RS485, MODBUS-RTU (standard), PROFIBUS-DP (optional), TCP / P (optional)  Control power capacity Single-phase 220 V AC / 3KVA, 50 / 60Hz (DC power supply can be selected according to project needs)  Main control functions Anti "power shaking" function, unit bypass, system self-diagnosis, automatic current limiting function, etc  Protection function Overcurrent, overload, short circuit, three-phase current imbalance, instantaneous power failure, input and output phase loss, overvoltage, under-voltage, overheating, external fault interlocking shutdown, unit automatic bypass, and reverse power protection Environment
