Pakistan’s National Power Control Centre is sending two engineers to China to learn about the Stability Control System for the north-south transmission line. This comes after the Chinese company M/s PMLTC, responsible for installing the system, declined to send their own engineers due to security concerns following a recent attack on the Dasu Project.
The SCS plays a vital role in maintaining grid stability by managing power fluctuations during disruptions. Regular studies are needed to determine safe power transfer limits between the north and south.
According to the Transmission Service Agreement, M/s PMLTC was initially obligated to conduct these studies in Pakistan and train Pakistani engineers. However, citing security concerns, they proposed sending NPCC engineers to China instead.
Pakistan has already shared summer power flow data with M/s PMLTC, and winter data is nearing completion. The engineers’ visit to China aims to finalize studies for both summer and winter scenarios by the end of August 2024.
In addition to NPCC’s efforts, Italian firm M/s CESI is also conducting system studies to determine the maximum power transfer capacity. Their report is expected by the end of July, with discussions on the findings scheduled for September before informing the Prime Minister’s Office.
This initiative is critical for ensuring a stable and efficient power grid. The SCS studies will be used to develop a comprehensive strategy for optimizing power transfer capabilities in the coming years.
