Utility interactive system using induction machines to supply mechanical power stored in solar batteries

Solar energy is a very attractive potential power source because of its clean and inexhaustible supply. However, the electric power that can be supplied by solar batteries is variable because it depends on weather conditions. Therefore, the supply is either stabilized by storing power in batteries, or it is added to the general utility network via an inverter. Such systems, however, have cost- and maintenance-related problems. This paper proposes a new utility interactive system that is composed of induction machine A connected to a solar battery through a general purpose inverter and another induction machine B interconnected to the utility line. The frequency of the inverter driving machine A is selected such that solar power can be maximally utilized. This system can supply a stable mechanical load with the required power by parallel operation of two induction machines even in rainy weather and, moreover, recharge the solar battery for the utility line in good weather. This proposed system is economical and useful as a small decentralized power supply because a power filter for rejecting high frequency noises and a detector for a power failure are not necessary. © 1997 Scripta Technica, Inc.

Interconnecting interactive and remote parallel components using schooner

In scientific applications where parallel computation is used to model physical processes, enhancing the user's ability to monitor and control programs executing on remote parallel machines can improve the overall experimental process. Here, a simple approach to providing such facilities is presented in which a scientific visualization system and a remote parallel computation are incorporated into a single metacomputation using the Schooner software interconnection system. This scheme gives the user the ability to, for example, select dynamically the parallel platform to be used, monitor the progress of the computation, and modify parameters. To illustrate this approach, a series of experiments is described in which the AVS scientific visualization system and a parallel neural net code executing on either an Intel Paragon, Sequent Symmetry, or PVM-based Sun Sparcstation cluster are interconnected. These experiments demonstrate not just the feasibility of structuring parallel computations as part of a larger metacomputation using Schooner, but also that these benefits can be achieved with an adjustable cost that can be tuned to the specific needs of the application. © 1997 John Wiley & Sons, Ltd.
