Dynamic models and analysis of overflow of upper level of GTS for their automatic protection
Abstract
A catastrophic increase in the supply channels of hydraulic structures on canals should be controlled, and automatic headwater protection from overflow should be carried out. Knowing the dynamic model of such a process, it is possible, according to a previously developed algorithm, to generate a control signal at the beginning of the transient process to prevent an emergency. The reasons were analyzed as threats leading to the overflow of the headwater, among which non-discharged sediments stably intensify the dynamics of the transition process. A control system simulation model was created in the MatLab environment, the coefficients were determined, and the dynamic characteristics of the pool overflow process were built. In this case, the time constant was 7 seconds, and the removal of the control signal was possible within 1-3 seconds after the start of the transition. Reducing the probability of a pool overflow threat is predicted to be within 25%.
