“…Discriminating, processing and utilizing transient fault information rightly is able to achieve high speed even ultra-high-speed operating performance (usually less than 5ms) [1]. However the relay protection that only uses transient fault information still remains in principle and algorithm research stage, and its practical application is difficult [2].…”

A transient fault information based IED integrating protection, fault location, fault record, measurement and control functions for transmission line is proposed in this paper. IED hardware scheme adopts multiple CPU distributed structure, and includes mainly the following modules: process level communication module, protection module, fault location and record module, measurement and control module, station level communication module and a MMI module. Transient fault information utilization is illustrated in detail, which mainly reflected in the protection module and the fault location and record module. Some key techniques are used to meet the smart substation development requirements. The multifunctional integrated IED can apply in the existing smart substations, improve protection performance and fault location precision, reduce equipment cost and operation and maintenance cost.

To protect the converters and minimize the power transmission interruption during DC line faults, it is necessary to detect the faults at ultra-high-speed for the MMC based HVDC grids. This paper reviews the state-of-the-art of DC fault protection methods of MMC HVDC grids, and summarizes the underlying principles of each method. On this basis, the DC fault characteristics analysis in terms of modal-domain, time-domain and frequency-domain are analyzed, which direct the protection design. Typical boundary protection and non-boundary protection schemes are reviewed. The advantages and disadvantages of existing fault protection methods are compared. A two-terminal MMC-HVDC prototype is developed to test the effectiveness of three fault protection methods. Comprehensive quantitative assessments of the protection methods discussed above are carried out in a four-terminal MMC HVDC grid. Finally, the future trends of the protection schemes are discussed and the findings are concluded.
