Exploration of Electrical System Design for Pile-Based Fixed Offshore Photovoltaic Power Stations
Offshore photovoltaic power stations have been developed in multiple coastal provinces of China,but there is no design specifi-cations for photovoltaic power stations in offshore scenarios.It is not appropriate to completely refer to the specifications compiled based on ground photovoltaic power stations for electrical design.Based on the analysis of the characteristics of offshore photovoltaic projects with fixed pile foundation,different application requirements are extracted,and the selection of inverters,subarray capacity,earthing sys-tem,and site selection of substations involved in electrical design are discussed.Suggestions based on the principles of using string in-verters,large subarrays above 6 MW,making full use of pile foundations as grounding electrodes,and appropriate site selection of substa-tions to reduce the amount of submarine cables are proposed.It can provide reference for the electrical design of offshore photovoltaic power stations with fixed pile foundation.
