Electrical power system having cluster transformer with plurality of primary windings

The invention relates to an electrical power system having a cluster transformer with a plurality of primary windings, in particular an electrical power system connectable to an electrical grid, comprising at least one cluster of electrical power subsystems. Each electrical power subsystem includes a power converter electrically coupled to a generator having a generator rotor and a generator stator. Each electrical power subsystem defines a stator power path and a converter power path for providing power to an electrical grid. The electrical power system also includes a single cluster transformer connecting at least one cluster of the electrical power subsystems to the electrical grid. A single cluster transformer includes a plurality of low voltage (LV) primary windings and at least one medium voltage/high voltage (MV/HV) secondary winding. 本发明涉及具有带多个初级绕组的集群变压器的电功率系统，具体而言一种能够连接到电网的电功率系统包括电功率子系统的至少一个集群。每个电功率子系统包括电联接到具有发电机转子和发电机定子的发电机的功率转换器。每个电功率子系统限定定子功率路径和转换器功率路径，用于向电网提供功率。电功率系统还包括将电功率子系统的至少一个集群连接到电网的单个集群变压器
