Title: Dam discharge monitor control method and dam discharge equipment control system
Inventor: SATAKE ISAO
IPC: G05D7/06
Filed: 1992-12-02
Abstract: PURPOSE:To improve safety by detecting whether the control target value is set normally according to the change of a water-level condition at the time of performing the feedback control of gate opening on the basis of the control target value, and correcting the control target value appropriately. CONSTITUTION:A discharge equipment input-output part 21 inputs signals from the opening gauge 13 of a gate 12 and a dam water level gauge 15 and outputs the operation signal of the gate 12 to a gate driver 14. The gate opening signal and dam water level signal are then inputted into a water level computing part 22 where the dam discharge quantity and inflow quantity are computed. On the basis of the computed value and the control set value of a setting element 24, a control arithmetic part 23 computes the control target value, and a gate control part 25 converts it into gate opening so as to output a control command to the gate driver 14 through the output part 21 while performing feedback control. A target monitor part 26 monitors the target value computed by the arithmetic part 23, and stops automatic control in the case of detecting abnormality and gives a warning to an operator. Excessive discharge can be thereby prevented, and discharge can be performed safely and positively.

Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To designate the magnetic axes in all speed range, and enable the continuous speed control by setting a specified magnetic axis coordinate and a specified designated magnetic axis with the specified space coordinates of a synchronous motor, and adding values with which a rotational speed command and an estimated speed value are multiplied by specified gains to it, thereby deciding the rotational speed of the designated magnetic axis. SOLUTION: A magnetic axis coordinate d-q (an axis which is advanced 90 deg. from the axis d is q) and a designated magnetic axis γ-δ (an axis which is advanced by 90 deg. from the axis γis δ) are set with the α-β space coordinates of a synchronous stator of a motor. Distribution gains K1 and K2 (K1+K2=1) are made as a function of a speed command, and the position of the axis γ is inputted into a vector control circuit 5b into a magnetic axis computing element 12, and the two-phase current of the synchronous motor 8 is inputted into a three-phase two-phase converter 9 to make a current on rotor coordinate γ-δ. Each estimated current value of the axes γand δ is inputted into an axis δ current controller 4 and an axis γcontroller 5, so as to make a voltage command.  Consequently vector control can be executed favorably, and it can be executed continuously with the same algorithm from the low-speed range to the high-speed range.
