DESCRIPTION

Based on the knowledge and experience acquired during almost 60 years of consulting, management, and design of High and Extra High voltage transmission systems, and taking advantage of the information systems advances and BIM technologies (Building Information Model), HMV Engineers has developed two complementary tools for computer based design: HMVTools and DISAC.

DISAC is a program AutoCAD-based platform that allows the development 3-D models of substations, including all main components like switchyard equipment, structures as columns and beams, insulators, bus bars, equipment connections, connectors, volume of buildings, etc.

HMV Tools integrates all calculations required for electromechanical, structural, and civil designs, which in addition to the above-ground substation also includes the underground systems such as foundations, grounding grid, drainages, cable trenches, and ducts. The model also incorporates the design of the grounding grid, lightning shielding protection, and magnetic field calculation, as well as verifying issues such as interferences, clearances violations, and also generates the project bill of material.Both programs store the information in a single model for the substation, in a secured company server, allowing that different work teams worldwide have access to the unique design of the substation model (design criteria, data, calculations and 3-D model).

HMV IN-HOUSE DEVELOPED SOFTWAREITEM SOFTWARE VERSION DESCRIPTION

1

DISAC

Version 4.0

Autocad based tool for the physical, civil, and electromechanical 3D lay-out of high voltage substations

2

HMV-Tools

Version 2.0

Software suite for the Integral 3D design for high voltage substations, including modules for busbar calculation, lightning shielding, grounding grid, magnetic fields, loads on structures, foundation design, trenches calculation, etc.

Both programs store the information in a single model for the substation, in a secured company server, allowing that different work teams worldwide have access to the unique design of the substation model (design criteria, data, calculations and 3-D model).

HMV Tools creates an automatic workflow, with facilities that allow registration of the phases of revision, versions, approvals, and quality control of designs; ensuring reliable results through the use of controlled procedures and data.
