Single Line Diagram of Mindanao island

Purpose: Research/Thesis
Date of Coverage: 06/27/2022 - 06/27/2022

Relleta 11:42 AM, Jun 27, 2022

I would like to ask for an updated National Power Corporation's (NPC) Mindanao Grid Single Line Diagram. As much as possible, the diagram should contain the following:

1. Generator Capacities in kW/MW/kVA or MVA
2. Transformer Ratings in kVA/MVA and winding voltages in kV
3. Transmission Lines showing the voltage (138/69/13.8 kV), conductor length and conductor size
4. Mindanao Grid Loads in kW/MW

My objective is to create a power system protection model for this network and use it to my research.
