کنترل بهینه فیلترهای توان اکتیو شانت در سیستم های برق صنعتی مالتی باس برای کاهش ولتاژ هارمونیک

The bus voltage and branch current detection control strategies of the active power filters used in industrial multibus power systems for harmonic voltage mitigation are analyzed and compared in the paper. The effectiveness of both the methods with real control gains is assessed in terms of the harmonic bus voltage mitigation and of the demanded current spectrum injected by the active power filters.
