In this article we will focus on creating of testbed based on hybrid real-time power system simulator (HRTSim) for setting up and testing of relay protection (RP), automatic (AS) and control systems (CS), as well as the opportunities and prospects of its application. The simulator has physical outputs, which allows using it for close-loop testing of RP, AS and CS. Physical currents and voltages generated in the simulator during a simulation process can be transmitted to the analog inputs of tested device by means of external amplifiers. There are no restrictions on the dimension of the simulated power system and time interval for HRTSim. These opportunities and usage of adequate models of primary and auxiliary power system equipment allows reducing the number of possible equivalenting and creating as closely as possible to the real conditions for setting up and testing of any RP, AS and CS, including wide-area protection and control systems.

With the development of wireless communication technology and computer technology, more and more smart technologies have been applied in electricity distribution networks. This paper presents an adaptive current differential protection and fast auto-closing system for application in 10 kV distribution networks in China Southern Power Grid. The current differential protection can adaptively change its settings according to the topology change of the primary distribution networks, thus the system effectively reduces the operation and maintenance cost of the power distribution network. In order to restore the power supply for the healthy part of the 10 kV networks quickly after a power system fault is cleared, the protection and control system provides wide area control function for automatic fault isolation and automatic switching. The traditional overcurrent protection and control system have no fault location function, it may take several minutes or even hours to manually locate a fault and then restore the power supply. Compared with the protection and control system of the traditional 10 kV distribution networks, the system developed can locate and isolate faults within 900 ms (assuming that the operating time of the load switch is 700 ms), and can quickly restore power supply in less than one second after a power system fault is cleared.
