FACTS devices are used to control the power flow, to increase the transmission capacity and to optimize the stability of the power system. One of the most widely used FACTS devices is Unified Power Flow Controller (UPFC). The controller used in the control mechanism has a significantly effects on controlling of the power flow and enhancing the system stability of UPFC. According to this, the ca...

The ability to detect and classify the type of fault plays a great role in the protection of power system. This procedure is required to be precise with no time consumption. In this paper detection of fault type has been implemented using wavelet analysis together with wavelet entropy principle. The simulation of power system is carried out using PSCAD/EMTDC. Different types of faults were stud...

Abstract This paper analyses the main factors affecting accuracy of double-end traveling wave ranging for high precision fault on cable lines in DC distribution networks, and points out that method segmented cables based uniform velocity is source errors. Then, an improved refined proposed. Based linear relationship between time difference location at both ends cable, measured segmental used to...

It is an effective measure for power enterprises to improve the voltage level of system by raising and lowering tap position main transformer. For parallel operation transformer, whole process adjusting must strictly meet conditions operation. Aiming at a case backup protection action transformer caused improper implementation regulation measures, this paper analyzes uneven load distribution in...

This paper presents a detailed dynamic phasor modeling process of line-commutated converter-based HVDC (LCC-HVDC) system. Firstly, the models single-ended LCC rectifier station, inverter station and DC line are established, respectively. Secondly, LCC-HVDC is an AC-DC-AC The interfaces explained to connect converter stations with line. Through block modeling, it helpful simplify verify accuracy...

A novel approach for VSI with an LCL output filter controller design for microgrids operating in grid-connected mode is presented in this paper. The controller structure is based on a multiloop control configuration in which the inner control loop is responsible for current regulation and the outer control loop generates the reference currents based on preset active and reactive power injection...
