Win-TDC* The State-of-the-Art Control and Protection System for HVDC Applications

Firstly, the design philosophy of HVDC control and protection system and the use of programmable digital controllers are discussed in this paper. Then the background for Win-TDC development is presented. For SIMATIC TDC based design, the consideration on lifecycle and distributed measurement are illustrated in detail. The characteristics of WinCC (HMI in Win-TDC system) and ibaScope (TFR in Win-TDC system) are also included in this paper. Finally as a conclusion, the improvements offered by Win-TDC are deduced in this paper
