Evaluation of System Constant Volume Controlby Zihui Lin,
David H. Manz,
Abstract: System constant volume control (SCVC) has been developed for optimal control of canal systems. The objective of system constant volume control is to maintain a reference storage (or target storage) for each reach (or pool) and to satisfy user's water demands by adjusting the control gate structures and turnout structures based on optimal operational decisions (such as optimal gate openings). A nonlinear programming (NLP) Model was used to make the optimal operational decisions for system constant volume control, with consideration of the canal's physical and operational constraints. System constant volume control has been evaluated using test cases set by the ASCE Task Committee on Canal Automation Algorithms (Kacerek et al, 1995). System constant volume control has been successfully tested by a flat and large canal under tuned and untuned conditions, respectively. The performance of system constant volume control was found to be excellent.
