Conventionally, the current flow control and DC fault protection issues of HVDC grids are supposed to be solved by the DC current flow controller (CFC) and DC circuit breaker (DCCB) separately, which may result in a high capital cost. This paper proposes a CFC topology with DC fault current limiting and interrupting capabilities. The topology and operating principle of the CFC are presented with theoretical analysis. The control strategies under normal and fault conditions are described. In order to reduce the use of IGBTs, an H-bridge inter-line CFC with fault current limiting capability is further proposed based on the proposed CFC. The proposed CFCs are tested in PSCAD/EMTDC. Simulation results show that the proposed two CFCs can effectively control the current flow of two lines during normal operation and limit and interrupt DC fault currents.

A high-voltage direct-current circuit breaker is a key equipment to construct a flexible direct current transmission system. Most of the existing design schemes have some shortcomings such as slow fault-breaking speed, poor current-limiting effect, large capacity of the arrester, and long reclosing operation time. To solve the above problems, this paper proposes an H-type high-voltage direct current circuit breaker with a current-limiting function. The current-limiting inductance is put into operation by judging the fault condition. It has good current-limiting ability in the process of fault-breaking and can maintain the dynamic performance of the power grid in the normal operation of the system. It has the advantages of fast fault-breaking speed, buffered energy consumption, early separation of fault points, and small capacity of the arrester. During reclosing operation, the transfer branch can be turned on at no-voltage. The different working states in the process of fault-breaking are analyzed theoretically based on the description of the topological structure and working principle. Finally, using the PSCAD/EMTDC simulation platform, the functional verification and system verification of fault-breaking and the reclosing operation process is conducted. Compared with the typical scheme, the simulation analysis shows the effectiveness and applicability of the function of fast fault-breaking and fault current-limiting.

Recently the hybrid multi-port DC circuit breaker (MP-DCCB) is becoming popular in protecting HVDC grids, thanks to their reduction of power electronics devices. In this paper, an enhanced multi-port current-limiting DCCB (MP-CLCB) for multiple line protection is proposed. The integrated fault current limiter (FCL) inside the MP-CLCB can clear the fault faster with slightly increased costs. To reduce the energy dissipation requirement for the surge arresters caused by the newly added current-limiting path, an energy transfer path which provides a loop with the inductors during the current decay stage is designed. The theoretical analysis of the precharging, current-limiting, fault interruption and energy dissipation of the MP-CLCB is carried out. Moreover, the design principles of the energy dissipation and the key parameters of the MP-CLCB are provided. The proposed approaches are verified through simulations in PSCAD/EMTDC. The results show that the MP-CLCB can replace multiple DCCBs, accelerate the fault current interruption and reduce the energy dissipation requirement for the surge arresters.
