A PLANT FOR TRANSMITTING ELECTRIC POWER |
摘要 |
<p>A plant for transmitting electric power comprising a direct voltage network (100) and at least one three-phase alternating voltage network (101 ) connected thereto through a station (102). This station comprises a Voltage Source Converter (103). A unit (104) is configured to control the converter according to a PWM pattern for generating an alternating voltage having a third harmonic voltage part added to a fundamental voltage part. No transformer is arranged between phase outputs (106) of the converter and the alternating voltage network (101 ). An arrangement (107) is configured to block said third harmonic voltage part and prevent it from reaching the alternating voltage network.</p> |
