چکیده
This paper deals with the shunt compensation design of long 380kV-50Hz XLPE cables by simulating a double-circuit partially cabled connection with the transmission length of 80 km in the Dutch transmission system. The proposed procedure for shunt compensation sizing is fully elaborated in this paper. Four sizing criteria are used to find the minimum required size of compensation. All simulations are performed for different cable lengths. Moreover, different compensation arrangements including line-end and distributed arrangements are compared in terms of minimum required compensation size. Finally, the influence of mixed-line configuration, i.e. the number and the location of cable sections, on the minimum required compensation size is investigated by simulating five mixed-line configurations. All simulations are performed for two load-flow scenarios representing two extreme situations in the future planning of the Dutch transmission grid.

Lightning Protection of Ehv Substations in Iran
Extra high voltage (EHV) substations are extremely vulnerable to the hazard of lightning strokes therefore, the shielding of these substations with a highly reliable protective scheme (shield wires) is an essential undertaking. In this paper an attempt is made to clarify the design procedure for shielding EHV substations against lightning with special reference to Iran.
متن کاملUltra-Widband Distributed Amplifier Using Loss Compensation Technique on Both Input and Output Circuit
In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s characteristics such as attenuation factor, phase constant and gain. The proposed design approach enables us to examine the tradeoff among the variables, which include the type an...
