摘要：
The paper deals with the demonstration of the fact that the emergency modes that occur in the pipeline networks are accompanied by wave processes resulting in the variation of all parameters of the hydrosystem. We worked out the mathematical model of the automatic control system with the function of the pressure stabilization at the consumer. We obtained the curves representing the alteration of the dynamic processes in the pumping complex during emergency modes occurrence. We formulated the diagnostic signs and proposed the algorithm of the determination of the emergency modes.
