✦ Synopsis
many advantages, such as excellent performance and enhanced safety. The performance improvement is achieved because of strong mechanical integrity (cycle life) and absence of binder (shelf life) in C-C composite. The enhancement in safety comes from high thermal conductivity, fire retardant characteristics and an acceptable ability to overcharge and overdischarge. Makino, H.

02/01486 Contingency rankingfor voltage collapse using parallel self-organizing hierarchical neural network Pandit, M. et al. Electrical Power and Energy Systems, 2001, 23, (5), 369-379. On-line monitoring of the power system voltage security has become a vital factor electric utilities. This paper proposes a voltage contingency ranking approach based on parallel self-organizing hierarchical neural network (PSHNN). Loadability margin to voltage collapse following a contingency has been used to rank the contingencies. PSHNN is a multi-stage neural network where the stages operate in parallel rather than in series during testing. The number of ANNs required is drastically reduced by adopting a clustering technique to group contingencies of similar severity into one cluster. Entropy based feature selection has been employed to reduce the dimensionality of the ANN. Once trained, the proposed ANN model is capable of ranking the voltage contingencies under varying load conditions, on line. The effectiveness of the proposed method has been demonstrated by applying it for contingency ranking of IEEE 30-bus system and a practical 75-bus Indian system.

Niwa, S. C02 Koteika, Kakuri no Saishin Gijutsu, 2000, 247-259. (In Japanese) Edited by Inui T. Conceptual design of natural-energy-based power generation systems is described, in which CO2 from coal-fired power plants is liquefied and hydrogenated to form MeOH for power generation systems. H2 needed for the above MeOH synthesis process is produced by water electrolysis with power supply from natural energy power generation systems using hydraulic or solar power. The system's economic feasibility is evaluated. Kordesch, K. et al. Journal of Power Sources, 2001, 96, (1), 200-203. A new approach for direct methanol-air fuel cells (DMFC), with the advantage of reduced crossover is discussed in this paper. Methanol traces in the circulated electrolyte are recovered and COz bubbles in the cells are removed due to the forced methanol-electrolyte stream through the cell. Degradation of the catalyst is reduced since fuel cell electrodes degrade on activated stand without load to a higher extent than under load because high voltage on open circuit promotes carbon oxidation, catalyst changes, etc. Therefore, life expectancy increases with circulating electrolyte by removing the electrolyte from the cells between operating periods.
