The Russian R&D Program for superconducting power devices is underway, supported both by government and electric power companies. In this program R&D on HTS power cables is considered as most advanced and close to commercialization. In the framework of the program, several, heavily instrumented, 5 m cables have been tested following by the 30 m - 3 phase experimental power cable development and testing in 2008-2009. The latest achievement is development and testing of the first long length 3 × 200 m power cable with rating 1.5/2 kA-20 kV. In parallel with just the cable development the innovative cryogenic system has been developed as well for the cable cooling. The system is using neon as working substance and radial turbo-machines in refrigerator. Cooling power is up to ∼8 kW at 65 K, inter-maintenance time ∼30,000 h. The cryogenic pump with superconducting motor can be used to provide subcooled liquid nitrogen flow ∼0.1-1.5 kg/s at 0.1-2.5 MPa pressure. After extensive tests at special test facility, HTS power cable and cryogenic system are planning to be installed at some substation in Moscow utility grid. In this review some details about Russian HTS power application program, 200 m cable and cryogenic system designs and tests results are presented. Source

A generalized structure of an algorithm for measuring the power-quality indices is examined. The specific features of the algorithm's blocks and possible ways to interpret it for different purposes and soft- and hardware abilities are shown. Ways to test the algorithm at every stage of development (from verification of the mathematical model to software debugging) are described. We analyze the algorithm's operation in the LabView environment for measuring power-quality indices. A multifunctional device for measuring power quality in accordance with GOST (State Standard) 30804.4.30-2013 is presented. Bench tests of the multi-functional device under different operating conditions and when carrying out different functions in the frame of one soft- and hardware platform are carried out. © 2014 Allerton Press, Inc.
