The solution of the problems is based upon the implementation of two optimal reactive power flow (ORPF) programs: the first relevant to determining a workable state (security aspect); and the second relevant to attaining the optimal and secure point (global target). The first ORPF is solved by recursively employing a linear programming algorithm, whilst the second is based on the Han-Powell algorithm. In the paper, emphasis is given to the introduction of the contingency constraints in the ORPF models. The N-1 security constraints are explicitly introduced in the programs in order to obtain an operating point preventive-secure with respect to a selected contingency set. The performances of the procedures are shown by presenting the numerical results obtained from their applications to a small test network and to the large ENEL transmission system. >","PeriodicalId":241767,"journal":{"name":"Proceedings.

This new technique is based on defining and identifying the waveform patterns of tlie voltage transients following initial breaker opening. It has the ability to distinguish between a permanent and a transient fault, and to optimize the reclosure time. Included within the proposed adaptive autoreclosure scheme, an emphasis is placed on detailed simulations of the whole process of fault autoreclosure sequences with the incorporation of realistic arc models to assess the performance of the proposed adaptive Single Pole Autoreclosure (SPAR) scheme. In the conclusion, tlie paper presents some interesting simulation results relating to a 500kV system subjected to various transient and permanent fault conditions.","PeriodicalId":241767,"journal":{"name":"Proceedings.
