“…The paper [60] used the sequence components of currents to detect the fault in the microgrid. Where the zero-sequence component of the current was considered in case of a single line to ground fault, while the negative sequence component of the currents was considered for the double line faults.…”

“…Due to the chances of loss of data or possible communication failure, differential protection will need a distinct backup safety method which increases the total size and cost of the safety method to limit its utilization in microgrid. The main protection problem related with microgrid is that the fault currents are low in islanding mode than in the grid-connected mode [21].…”

A cluster of distributed generation (DG) is a Microgrid (MG) and load which acts as a heavy load or source in the context of actual grid. The sudden gust in the microgrid causes rise in fault current which surpasses the shortcircuit limit of network equipment by microgrid connection and also the increase in penetration of DG into the grid, the fault current level is also increased simultaneously. In order to overcome this problem, fault current limiter (FCL) could be arranged between the main network and microgrid. There are different types of FCLs, which have various designs and are made of various superconducting materials. Superconducting Fault Current Limiter (SFCL) is revolutionary protective device which has the ability to lower the fault current level within the fault current first cycle. The application of the SFCL would not only reduce the burden on network devices, but also offers connection for the betterment of the power system reliability. SFCL's are broadly classified into three types: inductive, resistive and hybrid SFCL. In this paper, general characteristics of FCLs, the operating characteristics, current limiting capabilities of SFCL are introduced into a simplified microgrid model system which is finally allowed that SFCL could reasonably bring about the function of microgrid stability improvement and fault current suppression.

“…However, the current information system only describes the power equipment and does not include the auxiliary facilities of power equipment, and the managers cannot grasp the environmental information and overall situation of power equipment [12]. 3D GIS can display relevant data information in a 3D way, such as the positional relationship between iron tower and conductor, the electrical gap between conductor and ground wire, and the distance between conductor to ground and crossing distance [13]. 3D GIS can deal with more and more complex 3D spatial data more truly and intuitively [14].…”

With the rapid development of the power system and the increasing complexity of the power grid structure, users’ demand for information-based management of the power distribution network is growing, and the need to improve various power production service standards is becoming increasingly urgent. Geographic information systems (GIS) are a natural combination of geographic and data attributes that are particularly well suited to the management of urban pipeline systems such as distribution and telecommunication networks. This paper discusses the current application characteristics and challenges of 3D GIS in the power system. A 3D graphic analysis model of the power grid and its realization method are proposed using 2D GIS and scene simulation technology combined with object-oriented design method. The problems that exist in current urban distribution facility management are solved in this paper through the effective integration of information construction and distribution facility management, and the goal of refined management is achieved on this basis. More and more complex 3D spatial data can be processed more realistically and intuitively with 3D GIS.
