HVDC Transmission-Advantages & Disadvantages

DC transmission is an effective means to improve dynamic system performance. HVDC transmission consists of two converter stations which are connected to each other by a DC cable or an overhead DC line. By varying the firing angle (α), the DC output voltage can be controlled thereby controlling the power flow. In DC transmission, the … Read more
