As a part of the federal Government's policy of modernizing the electrical grids, each transmission operator has to assess the precise physical properties of their high voltage transmission lines. This assessment can facilitate in achieving operational excellence by reducing the associated risks. Using fashionable technologies like LiDAR, its potential to exactly map the transmission assets and predict changes based mostly on numerous parameters. The vegetation risk may also be identified by using Transmission LiDAR.
According to the federal mandate, simply identifying the vegetation risk won't be enough. The utility conjointly has to prioritize and commit to take away the vegetation that may be a risk to the transmission lines. To confirm compliance, an audit able arrange of action conjointly has to be created. Doing of these isn't potential by the standard ways.
On the opposite hand, fashionable remote sensing techniques together with state of the art analytics software facilitate utilities to require the precise inventory together with the correct location of all substations, conductor and transmission towers with their actual geographical location. Moreover, Transmission LiDAR conjointly helps in analyzing numerous on- field threats and provides the ways that to get rid of those.
Modern technologies like airborne LiDAR are employed for the purpose of identification and mapping of the assets, ancillary structures and vegetation cover of a utility. But only data collection is not enough. So business analytics software is used to transpose this data into digital three dimensional models of the utility. This model is capable of determining line sag under different operating variables. As a result it is the perfect tool to detect unforeseen risks as well as realizing untapped potential of the utility.
The entire process is done in four stages. The first stage identifies the vegetation of the utility by Transmission LiDAR. It also involves preparation of the digital models from the collected data. The next step asses the risk by carefully analyzing the 3-D models. The measurement and prioritize of the risk factors are also done on this stage. In the third stage scheduling of risk removal is done. This stage also deals with executing the risk removal. The final stage involves documenting the entire procedure and auditing it. It is also checked if the work was done maintaining all the federal specifications.
