A Hydropower Company has started to produce electricity during high demand peak hours releasing the daily volume for irrigation in few hours. Downstream of the storage dam, a Diversion dam stores the water released for power and delivers the water as the irrigation district requires under controlled conditions. Because of these changes in operations at the diversion dam a SCADA systems was installed. The measurement and operation equipment integrated for this application consisted in a SCADAPack, the Probe ultrasonic level sensor, gate position sensor and Horizontal Doppler Current Profiler Channel Master as flow meter. The SCADAPacks at the flow meter and diversion dam were connected by low cost radios called Maxstream. To improve the reliability of the systems redundant equipment was installed on gate position, upstream level sensor. For flow measurement reliability the gate equation, calibrated with the H-ADCP data, was used. As a first step a set of rules were introduced to adjust the gate opening to keep the flow at the head of the main canal constant as the level on the diversion dam change. Since the end of 2006 the system is being transferred from a manual system to an automated system.born digitalCD-ROMsproceedings (reports)engCopyright and other restrictions may apply.
