   ADJUSTABLE SPEED DRIVE PERFORMANCE EVALUATION METHODS
By H. B. Püttgen; P. Wung; D. Rouaud; E. Lajoie-Mazenc; J. Maire; M. Dessoude; M. Samotyj [View]
[Download]

Abstract: Electric Power Research Institute (EPRI) and Electricité de France (EDF) are cooperating to establish a set of systematic laboratory and field Adjustable Speed Drive (ASD) performance evaluation procedures. Both partners are conducting several performance evaluations of commercially available ASDs in an effort to establish and validate systematic laboratory and field test procedures.

   THE COMMERCIAL AND EDUCATIONAL BENEFITS OF VARIABLE-SPEED DRIVE TESTING FACILITIES
By A. K. Wallace; R. Spée; G. C. Alexander [View]
[Download]

Abstract: The paper describes a test bed for small drives (10 hp) which has been operated with considerable success for seven years as a service to industry, power utilities, and government agencies. The interaction between the operation of a test facility within the university and the functions of an instructional environment has been especially beneficial in promoting student interest in motors and drives. Adaptation of the techniques of the test bed have been incorporated in to contemporary teaching equipment thus expanding power engineering education at a time when many electrical engineering schools in North America have virtually abandoned energy related aspects of their programs. Currently, the need to promote efficient energy usage is recognized by the U.S. Department of Energy and most major power utilities who are to fund the development of larger test facilities to evaluate the qualification of newer technologies for rebate programs. Details of plans for test beds for motors and drives up to 300 hp are given and intended applications are described.

   FACTORY AND SITE TESTS ON THE 25 MW GTO POWER AMPLIFIER FOR THE CONTROL OF THE JET PLASMA VERTICAL POSITION

Abstract: The vertical position of the JET plasma is normally unstable and feedback stabilisation is therefore needed. A new power amplifier (Fast, Radial Field Amplifier - FRFA) based on GTO inverters bas been procured to cope with configurations characterized by plasma having a high degree of vertical instability, beyond the stabilising capability of the phase controlled thyristor converter used so far. The new power amplifier is composed of four identical subunits which can be connected in two different configurations to achieve output voltages up to 10 kV (at 2.5 kA) and output currents up to 5 kA (at 5 kV). The amplifier is characterised by a peak output power of 25 MW and by switching frequencies of the individual GTOs of 1 kHz. The series connection of more inverters allows more voltage levels (up to nine) to be made available on the load. The paper presents the results of the extensive series of tests on a dummy load performed on the amplifier both at factory, where a complete subunit was assembled, and at the JET site. The tests included the achievement of the full performances and the assessment of the correct operation of all the required control modes.

   HIGH POWER STATIC CONVERTERS AND AUTOMATION SYSTEM FOR FUNCTIONAL QUALIFICATION TEST STAND OF ELECTRONIC RAILWAY VEHICLES
By E. Elice; C. Gallandt; F. Ghislanzoni; V. LoVerde; M. Sommani [View]
[Download]

Abstract: A Test Plant at Ansaldo Trasporti (Neaples) has been built up, with the aim to conduct the functional qualification tests of railway vehicles at full load. It comprises a variable dc voltage fully regenerative static power supply (rated 4200 Vdc, 4000 A), four roller banks, equipped with regenerative dc drives (each one rated 1500 KW), and an automation system, based on two levels. This paper describes the characteristics of the power supply and of the automation system. The static power supply is composed by two 12 phase series connected thyristor converters with a dc output filter limiting the dc harmonics content. lts control system is asked to modify the dc output voltage according to laws that simulate the railway dc line variations. The automation system has a level 1 composed by four PLC's controlling respectively the roller banks dc drives, the main power supply and the electrical distribution, and a level 2 for tests management, data acquisition and operator guide.
