GRIDMC – Powerful Instrument for Power Utilities GRIDMC (standing for Grid Monitoring Center) is a unique information system (IS) for transmission line monitoring, data storage, management and interactive use. GRIDMC integrates various types of data creating a clear picture and providing deep insight into the state of the power grid with a possibility of managing objects’ certificates, equipment references, detecting defects as well as conducting maintenance planning. For the right information to be available to the right person or computer in more than one location within short amounts of time, GRIDMC operates on Internet/Intranet basis without the necessity of purchasing special software and time-consuming personnel training. The stored information can be shared and interchanged with other GIS systems as well as new data can be added either interactively in the local system or remotely through the Internet. The graphical part of the IS includes such object’s data like power line route on a geographic map, power line plan and profile, digital photos of the object. Attributive part of the IS contains a tower schedule, a clearance chart to the ground and crossed objects (power transmission lines of lower voltage, communications, civil networks and facilities). The user creates a schedule of defects as a reference application based upon the data of various surveys of the object’s technical condition. IS architecture provides for importing any object data obtained upon instrumental survey performance (ALS, Infrared thermography, CoroCam, etc), inspection checks, and line service. By utilizing data accumulated in IS the user may promptly, rationally and efficiently control power transmission resources basing on the precise and reliable information on the object: • coordinates of critical sections where conductor clearances to the ground, crossed objects, trees and bushes do not comply with safety requirements; Other documentation available to the user through GRIDMC includes: • data on the spans where conductor tension is insufficient and increased sag limit maximum use of power line load capacity; • data on detected line sections where natural objects, civil facilities are located in direct/dangerous vicinity to power line conductors and structures; • precise data on conductor attachment points elevation, structure coordinates, actual size of glades in forest and park areas, vegetation height and location of trees dangerous to power transmission line; • tower deviation off vertical, and structure’s cross-arm – off horizontal position; • evidence of dangerous ground erosion near structure foundations; • potentially critical areas of power objects’ submergence at various levels of flood in nearest rivers and ponds.
• power line profiles with contours of terrain and vegetation layer; • topographic plans with the power line identified, orthophotos, 2D and 3D visualization of objects; • “virtual reality” three-dimensional representation of power transmission lines and all objects in the right of way; • tables containing information about crossings with other power lines, communication lines and waterways; • schemes of conductors phasing and transposition; • photos and drawings of the structures. The user can easily make corrections and update the semantic information about the power line stored in the system (year of construction, modification, reconstruction; various subcontracted organizations). Special modules allow the following functions: • storing LIDAR data as 3D-points, grids, etc.;
• representation of LIDAR data as graphical objects on a topographic map and/or as spreadsheet tables, objects’ certificate items; • navigation between the different representational forms of the same object; • creating searches and queries with results export into MS Excel format; • carrying out various data modifications with further automatic adjustments of the associated parameters; • exporting data to PLS-CADD for analysis and modification and importing the modified data back to GRIDMC; • exporting LIDAR data to the XLS and/or XML formats; • importing LIDAR data from the XLS and/or XML formats; • direct export of GRIDMC stored data into elaborated in-house 3D viewer module available as a stand-alone application; • efficient collection, storage, integration and representation of ground survey/inspection data. You can also form various reference directories and classifiers sorting the data by the following parameters:
• identified defects and performance breakdowns;
• manufactures of power lines elements; • climatic conditions and exterior influence; • other configurable parameters. |
