Controle de escoamento em instalações de condutos forçados.

Escoamento
Abstract in Portuguese
Este trabalho compõe-se de duas partes essenciais. Na primeira parte sistematizamos o equacionamento de uma rede hidráulica genérica, de tal forma a descrever o seu comportamento dinâmico por um sistema de equações diferenciais não lineares de primeira ordem. Este sistema engloba as características físicas e morfológicas da rede, a(s) vazão (ões) de água tratada que alimenta (m) o sistema, a demanda populacional, e a vazões e pressões operacionais . Na segunda parte definimos e apresentamos uma solução simplificada para um problema de controle encontrado na maioria das instalações. Trata-se de operar um sistema de distribuição, de maneira a compatibilizar, a cada instante, o esquema de produção, definido pelas características da (s) estação (ões) de tratamento de água que o alimentam, com as operações das estruturas de controle e das estações de bombeamento, de maneira a atender o consumo populacional, durante um dado período, evitando-se o extravasamento ou esgotamento dos reservatórios.

Abstract in English
This work is composed of two Essentials parts. In the first one we systematize the equations related to a generic hydraulic network, in such a manner that its dynamical behavior is described by a set of non-linear differential equations. This system includes the physical and morphological characteristics of the network, the flow of the water supplied by the treatment stations, the populational demand for water, and the operational flows and pressures. In the second part we define and present a simplified solution of a control problem found in most installations. This problem is concerned with the control of a distribution system in such a way to became compatible, at every time, the production plan of water, defined by the characteristics of the treatment stations, with the operation of the valve structures and pump stations. This is done in order to attend the populational demand for water, in a given period, keeping the reservatoirs oscilating within theirs operational limits.
