Abstract: Researches of the dynamic processes happening in the pump station of autonomous system of water supply are conducted. The pump station is considered as a nonlinear dynamic control system with cross feedback. As indicators of quality of work of system, critical for the choice of the equipment, are chosen dynamic water level in the well and number of turning on of the pump in an hour. For the analysis of transition processes and quality indicators of system his mathematical model in a package of visual modeling Xcos as a part of the software of Scilab is constructed. The parametrical analysis of characteristics of model in working conditions with a limited output of the well is made; methods of assessment of quality and the choice of the equipment by criteria of ensuring no-failure operation of system in various operational modes are offered.
