Embodiment Construction

[0015] like Figure 5 As shown, this embodiment relates to a method for ship shore power parameter design and performance evaluation, including:

[0016] ①According to the port type, analyze its geographical location, natural environment, port layout and berths and other characteristics, and analyze the type of docked ships and load characteristics.

[0017] ② Based on the analysis results of the port type and the characteristics of the berthed ships, the scheme design is carried out from the two directions of the system structure and the key parameters of the system at the same time. In terms of system structure, with the goal of optimizing the operation of the port shore power system, the grid structure, boarding method and grounding method of the port shore power system are selected and designed in turn;

[0018] ③ In terms of key parameters of the system, the electrical system, optimal voltage level and filter parameters are selected, calculated and designed in turn, and ...

Abstract

The invention discloses a ship shore power parameter design and performance evaluation method and device, and the method comprises the steps: respectively designing a corresponding grid structure, a boarding mode, a grounding mode, a corresponding power system, an optimal voltage grade selection and a filter after port features and ship features are obtained through port feature analysis, and obtaining a port shore power system design scheme; starting from the electrical design of the shore power system, the parameter design method of the ship shore power system is provided from four aspects of voltage grade selection, grounding system design, wire system design and filter as well as a shore power system design process and a typical shore power system design scheme.

Description

technical field [0001] The invention relates to a technology in the field of shore power, in particular to a method and device for parameter design and performance evaluation of ship shore power. Background technique [0002] The technical completeness of existing shore power related products has been gradually improved, and the ability to meet the needs of marine load power supply applications has been continuously enhanced. Domestic ports such as Shanghai Port, Lianyungang Port, Shenzhen Shekou Port and Ningbo Port have carried out preliminary exploration of shore power demonstration projects. However, there are still problems in the shore power technology, such as the immature ship shore power connection technology, the insufficient guarantee for the safe operation of shore power equipment, and the imperfect test system of the shore power system. There are a series of problems in the shore power technology system based on engineering application services. key technical re...
