Problems solved by technology

At the same time, the procedural language method is too complicated and has high requirements for users, which is not conducive to users' learning and use; because the expression is calculated by using simple cycle calculations, the order of calculation calculations is strictly required

Embodiment 1

[0055] When a variable in a substation changes:

[0056] The a1 variable in the total active power formula of substation 1 changes;

[0057] Modify the value of variable #1 in the total active energy formula of substation 1, and mark that the active energy total formula of substation 1 needs to be calculated;

[0058] The system triggers the total active power formula of substation 1 to calculate and save and remove the calculation mark;

[0059] Since the total active power variable of the substation 1 changes, this will inevitably lead to a change in the total active power variable of the substation 1 in the total active power of the system, thus triggering the calculation of the total active power formula of the system.

Embodiment 2

[0061] When two variables in a substation change:

[0062] The variables a1 and a2 in the total active power formula of substation 1 change;

[0063] Modify the values ​​of variables #1 and #2 in the total active energy formula of substation 1, and mark that the total active energy formula of substation 1 needs to be calculated;

[0064] The system triggers the total active power formula of substation 1 to calculate and save and remove the calculation mark;

[0065] Since the total active power variable of the substation 1 changes, this will inevitably lead to a change in the total active power variable of the substation 1 in the total active power of the system, thus triggering the calculation of the total active power formula of the system.

Embodiment 3

[0067] When a variable of data in two substations changes:

[0068] The a1 variable in the total active energy formula of substation 1 and the b1 variable in the active energy total formula of substation 2 change;

[0069] Modify the value of substation variable #1 in the total active energy formula of substation 1, and mark that the active energy summation formula of substation 1 needs to be calculated, modify the value of substation variable #1 in the active energy summation formula of substation 2, and mark the active energy of substation 2 The sum formula needs to be calculated;

[0070] The system triggers the active energy summation formula of substation 1, and the active energy summation formula of substation 2 is calculated and saved and the calculation mark is released;

[0071] Since the total active power variables of substation 1 and substation 2 change, this will inevitably lead to changes in the total active power variables of substation 1 and substation ...

Abstract

The computational method of a electric power attemper automatic system computation quantity data was involved in this invention, which was realized by the following steps: The calculates quantity data should be processed to the formula edit and translated into the formula marshal; Formed variable marshal, established the corresponding relations between variable and the formula; The variable data change triggered formula; in the variable marshal, some value changed, gained the change data, revised the corresponding variable value and marked the formula, triggered the formula; Computed the formula which has triggered mark, then preserved the computation value, and relieved the mark; Waiting change information of the next time the variable data to trigger the formula computation. This invention method does not rely on computation order of the computation quantity, adopt the triggering mechanism to compute triggering the computation quantity data formula by the variable change information, the resources utilization rate of system was improved, the system's load was reduced, it can satisfy the user's mass timely data computation request, does not rely on details electric power attemper platform, and it was easy to promote.

Description

technical field [0001] The invention relates to the technical field of electric power automation systems, in particular to a calculation method for calculation amount data of an electric power dispatching automation system. Background technique [0002] In the field of power system, the power dispatch automation data acquisition and monitoring control system (SCADA) is the most basic part of power dispatch automation. In the SCADA system, it is required to be able to complete the processing of calculation data, which is an important component of SCADA data. part, which includes statistics and evaluable quantities. [0003] At present, there are two ways to calculate the amount of calculation data commonly used at home and abroad: one is to imitate the grammar of C / C++ or other languages, provide users with a process language for formula editing, compile and produce object codes that can be recognized by the SCADA system, and then SCADA The system calls periodically. The ot...
