Compensator rating for radial distribution lines
34% of the South African population is still without electricity. Most of these people stay in deep rural areas where the cost of electrification is very high. Radial lines are characteristic of rural networks and methods to stretch existing lines or constructing cost-effective new networks are of high priority. Cheap conductors with large voltage drops and voltage regulating network devices are on the forefront of research in rural electrification. Network devices are classified as one of four generic devices, namely shunt, series, series-shunt and in-line devices. The paper proposes a method in which all solutions to a specific voltage regulation problem can be evaluated to determine the best solution. The Cathedral Peak case study is presented as a working example.
In the wideband radar system that can obtain one dimentional range image of the target by using STRECTH pulse compression,all kinds of system errors leading to the rise of the side lobe and the broadening of the main lobe degrade the images.So it is necessary to compensate these errors.This paper introduces a radar universal processing module which adopts 4 chips of ADSP-TS201 which is made by ADI as central processor and one chip of VIRTEX-IIPRO series FPGA as coprocess.Based on radar universal processing module,a method of systematic compensation is given.This paper presents a engineering realization through some datas of a wideband radar.This method shows a good effect and is used in a certain radar.
