Problems solved by technology

[0004] However, the traditional AGC software has a high degree of coupling with the hydropower station monitoring system software and communication methods, and the on-site implementation is cumbersome. The cycle timing execution method is adopted, the program execution efficiency is low, and the response rate is slow. ; In order to solve the above problems, the application proposes a script scheduling calculation method for the AGC control device of a hydropower station

Embodiment 1

[0034] Such as figure 1 As shown, the present invention provides a script scheduling calculation method for AGC control devices of hydropower stations, comprising the following steps:

[0035] The script calculation scheduler built in the AGC control device schedules and calculates the script according to the script calculation strategy;

[0036] The script calculation scheduler judges whether the calculation result has changed, if not, ends the calculation of the current script, and scans the next script;

[0037] If so, the script calculation scheduler judges whether the current script has associated scripts, if not, ends the calculation of the current script, and scans the next script;

[0038] If yes, bring all associated scripts of the current script into the above steps until all scripts in the script file and associated script scheduling calculations are completed.

[0039] The script file in this embodiment is generated by visual editing based on the UI interface of ...

Abstract

The invention discloses a hydropower station AGC control device script scheduling calculation method. The method comprises the following steps: performing scheduling calculation on a script according to a script calculation strategy; judging whether the calculation result is changed or not, if not, ending the calculation of the current script, and scanning the next script; if yes, judging whether the current script has an associated script or not, and if not, ending calculation of the current script, and scanning a next script; and if yes, substituting all the scripts associated with the current script into the above steps until all the scripts in the script file and the associated scripts are scheduled and calculated. The response rate and expandability of the AGC control device can be improved, the hydropower AGC regulation rate, precision and reliability are improved, and the requirement of a power grid for the hydropower frequency modulation and peak regulation capacity is met.

Description

technical field [0001] The invention relates to a script scheduling calculation method of an AGC control device of a hydropower station, belonging to the technical field of automatic control of a hydropower station. Background technique [0002] With the construction of my country's smart grid and the large-scale integration of new energy sources with fluctuating and intermittent characteristics such as large-scale wind and solar power into the power grid, the frequency and peak regulation of the power grid and the pressure to accommodate them are huge, and more stringent frequency regulation and peak regulation rates have been proposed for hydropower. Improving the adjustment speed, precision and accuracy of hydropower AGC is of great significance for improving the flexibility of the power grid and ensuring the safe, stable and efficient operation of the power grid. [0003] The AGC software of traditional hydropower stations generally runs on the server of the computer moni...
