With the large-scale development of offshore wind power
the marine ecological imbalance caused by the wind farming operation is getting serious gradually
so it is of great significance to study the optimization of the collector system under environment restriction. In this paper
the whole-life-cycle cost of the collection system is taken as an objective
and the economic model is built to study the features of sea-cable magnetic field
which causes damage to the submarine electromagnetic environment
and a magnetic constraint value is set. In addition
the multi-party game evaluation of planning schemes is conducted from the respects of marine electromagnetic environment
economic cost and reliability
and the optimal planning scheme is obtained with economics
environment-friendly and reliability. The case analysis results indicate that the environmental constraint has an obvious influence on the optimal planning results.
