Abstract

PURPOSE:To raise the reliability of monitoring control system for dam by a method in which when the arithmetic results of the inflow of dam is negative, correcting data are extracted from a correction table provided in advance and correction is automatically applied to the arithmetic results. CONSTITUTION:For calculating the reserving amount of water DELTAV of dam, effluent amount Qout is calculated and then the calculation of dam inflow Qin=Qout+DELTAV is made. When the value of Qin becomes negative by measuring error, etc., DELTAV is cleared to zero if the value is negative even for the previous case, data on correction g(i,j) of corresponding timing are taken out from the table of the correction qin of dam inflow, and the values are taken as inflow Qin=q(i,j). In the subsequent steps 9 and 10, correction is made on reserving amount DELTAV so that the inflow Qin becomes qin. In the calculation of inflow, in case where arithmetic results opposing to natural phenomena are sent out, automatic correction is made, enhancing the reliability in monitoring control for dam.

As a result of the calculation of equation (1), the dam inflow amount Qin is calculated by the calculator 7.
is automatically calculated based on equation (1), so there are cases where the calculated value is negative. The main reason why the dam inflow Qin is negative is as shown in Figure 4. This is because the water levels H2fitQ are read from the flow meters 6 and are calculated online by the computer 7, so errors occur in the water levels H due to natural phenomena such as photographing the water surface of the dam 4 itself and wind.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, by adding the processes of steps 9 to 15 in Figure 1, in which the same parts as in Figure 3 are indicated with the same reference numerals, the inflow amount Qin is automatically corrected, and the storage amount accompanying the correction is added. A correction is also made to ΔV, and when the influence of the correction returns to normal, the original processing procedure is returned. Since the storage amount ΔV is often treated as an integrated amount, the effect at the time of integration is eliminated.

Next, the procedure for correcting the dam inflow amount according to the present invention will be explained according to the flowchart shown in FIG. First, step 8
Then, whether the inflow amount Qin is positive or negative is automatically determined. If the determination result is negative, it is determined in step 15 whether or not it was negative last time, and if it is the first time, the dam inflow counter ΔV is cleared to zero in step 16. Then, the data of the correction value '4cr,j) at the corresponding timing is extracted from the table of dam inflow correction values 9 inches shown in FIG. 2, and that value is taken as the inflow amount. Furthermore, the inflow meter correction value Qin table shown in FIG. 2 may be configured differently depending on the system. For example, one year, 18 units of average time data (2

In addition to the above example, the qin correction table shown in Fig. 2 can also be configured by dividing a day into hours, a year into seasons, etc., and creating a table based on the average value of the inflow of hourly data. . Since the output data from the measuring device is constantly measured and inputted to the computer 7 online (hourly, minute by minute, etc.), the data obtained from the measured data and the calculation results is the dam inflow Qin.
The value of (m/b) is calculated periodically. Therefore, the table used in the logic of this invention automatically calculates the average value of the value set in the table and the currently measured dam inflow amount and sets it in the table. That is, the currently measured dam inflow amount q(m/h) set in the table ``'(i, j) (m/h) resultant amount is set in the table as a new q(i, j)N.
