Davao Light and Power Company energized and put into service its newly reconstructed 69/13.8kV Victoria Power Substation last August.
This project is one step towards the company’s goal of standardizing the design of all its substations with two main features, according to Engr. Ronald Chan, assistant vice president for the distribution utility’s engineering group.
Aside from the usual rehabilitation, the reconstruction was purposely made to [1] convert existingsubstations to become mobile substation connection- ready, and [2] prepare its 69kV line to operate in a close loop system.
The reconstructed substation now provides space for a Mobile Substation necessary to carry the loads of the power substation if a major problem occurs specifically affecting the substation’s power transformer. This is designed to avert a prolonged power interruption which happens when a power transformer has to be repaired before restoration can be implemented.
Meanwhile, the other additional feature which is the 69kV close loop system will protect the power substation from being interrupted if a system disturbance happens in the 69kV sub-transmission line, its source of power supply. It will automatically draw ready alternate power from the healthy 69kV line with no interruption as a result of having the 69kV system capable for a close loop operation. In this way, the substation continues to have power while the line segment having problem is already isolated, thus, a more improved system reliability in place.
At present, upgrading works are being done to adjacent substations to make the 69/13.8kV Victoria Power Substation fully operational as closely monitored by Engr. Jaime Derecho, the project in-charge.
The completion of this project will be another milestone for Davao Light towards fulfilling its aim of providing the best possible service there is for its customers. Once again the company takes a closer look at its vision…. of becoming a world-class utility.
