Temporary support structures (UMKW) for power lines are used in emergency situations. Such system-based solutions require dedicated software that enables rapid design (model creation, calculations, and documentation generation). Achieving this goal involves adopting a data structure that minimizes the amount of input required from the designer while maximizing automation in each phase of the design process. This is made possible through the creation of a database of predefined and parameterized profiles for support structures. Design acceleration is enhanced by an advisory system that suggests and supervises the configuration of conductor suspension layouts, structure geometry (while maintaining electrical clearance requirements, both internal and external), structure height, etc. The declaration of load cases and their values is also fully automated. Based on data regarding conductors and insulators (retrieved from databases) and the line location within Poland territory (climatic zones), an analysis of conductors (cables) is performed, and all load cases required by standards, including variations leading to bending and torsion of support structures, are determined. The article presents two software variants differing in concept. The first variant involves a preliminary selection of structure imported from a database of pre-analyzed typical cases (UMKW-Base), while the second performs complete calculations (UMKW). The UMKW software system employs a dual data input module, enabling rapid design while achieving greater software versatility. Declaring the physical model of the structure and its automatic conversion to an analytical model allows structural calculations to be performed as well as preparation of design documentation without duplicate data entry.References
