Title:
CONTROL SYSTEM FOR OPEN CHANNEL
Document Type and Number:
Japanese Patent JPS59154504
Kind Code:
A
Abstract:
PURPOSE:To control an open channel with high quality by reducing the amount of calculations required to estimate transient variation in the state of the open channel due to variation in the quantity of intake water and applying the system to on-line control. CONSTITUTION:The section between gates of an upstream open channel is shwon by the model consisting of three water tanks 12, 14, and 16 and two conduits 13 and 15 connecting the water tanks together. Then, the quantity Qi of intake water from a high-priority side gate 17 and the quantity Qo of outflow water of a lower side gage 18 are regarded as environmental conditions. Then, the water level h1 of the upstream water tank 12, water level h3 of the intermediate water tank 16, flow rate Q1 of the conduit 13 connecting the water tanks 12 and 14 together, flow rate Q2 of the conduit 15 connecting the water tanks 14 and 16 together, and the quantity (q) of water diversion are regarded as the quantities of state. Then, those quantities of state are estimated on the basis of observed values regarding the water levels h1 and h3 of the water tanks 12 and 16 and the transient state of the open channel is calculated on the basis of the quantities of state.
