A water affair calculation method based on report engine

Abstract

The invention discloses a water affair calculation method based on a report engine, which forms a reusable report engine by encapsulating a water affairs calculation report function library in a bottom layer, comprising a basic report function library, a calculation report function library, a service report function library and a report format definition. The calculation process editing module designs the data template in advance and defines the types of source data and output data, so that the algorithm editing configuration, the operation calculation, the adjustment and the maintainence of the water affair calculation can be carried out quickly and easily.

Description

technical field [0001] The invention relates to a water calculation method based on a report engine, and belongs to the technical field of water regulation automation. Background technique [0002] Water affairs calculation is a basic content of hydropower plant reservoir dispatching and operation work, one of the basic functions of water dispatching automation, and the basis for hydropower plant analysis of operating conditions and assessment of operating results. Economic dispatch level needs. In order to improve the accuracy of water affairs calculation and ensure the timeliness of water affairs calculation results, all hydropower plants have basically established water affairs calculation software to computerize water affairs calculation work. [0003] Water affairs calculation usually automatically calculates the out-of-storage flow, power generation flow, discarded water flow, power generation head, etc. Common reservoir statistics and statistical indicators such as ...

AI Technical Summary

Problems solved by technology

[0010] 1) It is highly targeted, and different hydropower plants need to develop water calculation software separately;

[0011] 2) Since the algorithm and process are solidified in the software program, it is necessary to modify the software program when adjusting the algorithm or parameters, which has poor flexibility and inconvenient maintenance

[0013] 1) Using XML to configure the algorithm can realize simple logic calculations, but in the calculation of reservoir dispatching indicators, processes such as loops, iterations, and matrices are also used, so this method cannot realize complex logic control, configuration, and large-scale data statistical calculations. mechanism;

[0014] 2) The algorithm file is described in XML, and each calculation step The type is one of interface function, arithmetic arithmetic operation or logic operation. For example, the interface function needs to configure specific function names, parameters, etc., and a deep understanding of all interface functions is required. There are certain thresholds for algorithm configuration and maintenance.

[0015] From the above, it can be seen that there are certain defects in the current water calculation methods in the industry, which affect the further development of reservoir optimization and dispatching work.
