Method for editing load condition combination calculating formulas

Abstract

The invention discloses a method for editing load condition combination calculating formulas. The method is of a platform open type, allows free editing of the calculating formulas and can ensure safety and effectiveness of the formulas edited by a user and open parameters which the user can use to the maximum. The method includes the steps that 1, four conditions of normal running, construction operation, accident line breaking and special loads of a line are integrated, and the calculating states of the conditions are obtained according to the basic rule of load combinations; 2, a formula editing homepage is manufactured, wherein the calculating states are displayed on the left side of an interface in a tree control form, and corresponding calculating formulas are displayed through click; 3, a formula editing page is manufactured, wherein data needed by common calculation, basic calculation data, basic calculation coefficients and installing condition basic parameters are displayed on the interface; the current modified formulas are checked and used for reconfirming the formulas being modified currently and are compared with the formulas before modification.

Description

technical field [0001] The invention belongs to the technical field of transmission line engineering, and in particular relates to a method for editing formulas for combined calculation of load conditions. Background technique [0002] Load condition combination calculation is one of the core calculation modules in transmission line engineering. It is used to calculate the load combination under normal operation conditions, disconnection conditions, uneven icing conditions and installation conditions, and rare conditions such as earthquakes should be checked when necessary. . [0003] The load borne by the tower is generally decomposed into three types: lateral load, longitudinal load and vertical load. The lateral load is the load along the direction of the cross arm, the longitudinal load is the load perpendicular to the direction of the cross arm, and the vertical load is the load perpendicular to the direction of the ground. The combined calculation of working conditio...

Problems solved by technology

Since the calculation of the combination of working conditions depends on many regulations and specifications, the types of working conditions are complicated, and the calculation methods are changeable, the major electric power design institutes and provincial institutes also have their own exclusive calculation methods, which involve industry secrets and should not be disclosed.

If a set of exclusive calculation programs are developed for each power design unit, it will cost a huge amount of manpower and material resources
