Am. Schulte et Ap. Malm, INTEGRATING HYDRAULIC MODELING AND SCADA SYSTEMS FOR SYSTEM-PLANNING AND CONTROL, Journal - American Water Works Association, 85(7), 1993, pp. 62-66
The DuPage Water Commission (DWC) of Elmhurst, Ill., has built a new w
ater distribution network and is monitoring it using an integrated sup
ervisory control and data acquisition (SCADA) simulator (ISS). The ISS
integrates DWC's SCADA system and its hydraulic simulator to confirm
system design, develop operational scenarios, and train operators to r
espond to emergencies. Operations personnel have already verified the
accuracy of the hydraulic simulator, which enabled them to resolve an
operational problem involving a low-pressure system response. The ISS
has been demonstrated for initial system studies, for verification of
the transfer mechanism, and for actual storage management studies duri
ng unexpected drought strains on the system in the summer of 1992. Eme
rgency training through return of data from the simulator to the SCADA
system has been delayed. The training will enable an operator to simu
late a main break, for example, and practice alternative responses by
manipulating a system of remotely controlled isolation valves. Using t
he ISS, operators can become familiar with unusual conditions before t
hey occur in the real system, which began operation in January 1992.
