Simulação de cenários de operação de sistemas de distribuição de água através do método PNL2000.

Abstract

The operation of systems of water distribution comes assuming to each day a bigger together importance to the companies of sanitation and the users of irrigation structures. This has as justification the cost of the maintenance of networks ramified or threshed and the availability of the water, that in determined regions is each lesser time. Of this form, the simulation of this activity, in such a way has basic paper in the economic field how much in the social one. The methodology adopted in this work of dissertation was the Not Linear Programming from method PNL2000 (GOMES, 2001) for being a practical method and with already proven efficiency how much to the economic sizing of threshed networks. The edition of method PNL2000 and the results of the simulations i f process with the use of the electronic spread sheet Excel of the Microsoft and the tools of called optimization SOLVER. Method PNL2000 was applied the two existing networks of water distribution, one threshed and ramified other: the Great Ring of the Network of Water Distribution of the city of Recife-PE and Sector 11 of Irrigated the Perimeter Senator Nile Coelho in Pelrolina-PE, respectively. The results gotten through the use of method PXL2000 in the simulation had revealed efficient, supplying to the end a data set that if adjust with the reality of the used networks of supplying as application examples.
