DC transmission system in monopole-grounded return operation mode may cause DC magnetic bias of some transformers in AC power system. In order to develop the management measures of DC bias effectively, it is necessary to study the influence factors of DC magnetic bias current comprehensively. Based on the direct field-circuit coupled method, a simplified model of the AC power grid is established by...
This paper provides an algorithm based on the microhabitat theory and particle swarm for the problem of wide area controller parameters optimization. The method cans optimal parameters. According to multi-objects model of the problem, and reduce the difficulties and works in design for multi-machine power system damping controller. In the end of paper, a typical four-generator two-area testing system...
This paper provides a algorithm based on the microhabitat theory and particle swarm for the problem of transformer substation optimization. This method can locate the substation according to multi-objects model of the problem, give the best scheme in a certain load level, and reduce the difficulties and works. In the end of paper, a real project example is showed to prove the validity and feasibility.
