Embodiment 1

[0022] In the process of energy distribution, if the control system adopts the uneven coefficient method as the control strategy for automatic distribution, it will carry out the distribution of each unit time according to the uneven coefficient sent from the HMI (Human Machine Interface) interface of the host computer. and the unit time can be one hour, that is, every hour, the HMI will issue the unbalance coefficient of the hour, so as to calculate the distribution and loss of the hour. The calculation formula is as follows:

[0023]

[0024] Among them, FQ SP Setpoint for the flow in automatic dispense, FQ CDSP Designated daily gas transmission volume for the distribution station, FQ CD The daily completed gas transmission volume of the distribution station, Kt is the non-uniformity coefficient issued by the HMI software. The remaining amount is calculated from the daily designated gas volume minus the completed gas transmission volume, and then divided by the remainin...

Abstract

The invention discloses an automatic energy distribution and transmission method and device, wherein the method comprises of the following steps of acquiring a second nonuniformity coefficient corresponding to a next distribution and transmission time period in the distribution and transmission process according to a first nonuniformity coefficient corresponding to a current distribution and transmission time period; comparing the first nonuniformity coefficient with the second nonuniformity coefficient; and under the condition that the second nonuniformity coefficient is greater than the first nonuniformity coefficient, adjusting the nonuniformity coefficient of the target sub time period in the current distribution and transmission time period according to the second nonuniformity coefficient, wherein the target sub time period is a sub time period adjacent to the next distribution and transmission time period in the current distribution and transmission time period. The method and device provided by the invention solve the technical problems that during automatic distribution and transmission in the prior art, the differences between the nonuniformity coefficients of two adjacent distribution and transmission time periods are great, so that the fluctuation of distribution and transmission data is great, and the metering accuracy of a flowmeter is influenced.

Description

technical field [0001] The invention relates to the field of energy distribution, in particular to a method and device for automatic energy distribution. Background technique [0002] In the automatic distribution control of energy (natural gas, etc.), there is a distribution method called the non-uniform coefficient distribution method. The flow setting value is calculated every hour during the execution process. After that, the flow setting value will not change in the hour and will be calculated in the next hour. Therefore, when the data is switched in two hours, it will cause The problem of large fluctuations in data flow switching, and large fluctuations in data flow switching will cause the opening of the on-site adjustment valve to increase, which will cause the pressure behind the valve to increase, and in the case of safety protection, it will cause the cut-off valve to cut off. And the noise inside the pipeline is relatively large, which will eventually affect the...
