Abstract:

Power systems that utilise a significant proportion of renewable energy are currently confronted with a number of challenges, including congestion in the transmission line network, issues pertaining to the stability of power supply and synchronous power degradation. In order to address these issues, it is necessary to implement an advanced wide-area monitoring, protection and control (WAMPAC) system, which will enable the rapid determination of transient and steady-state conditions in power systems. The implementation of this system will facilitate adaptive control based on the results of online data analysis, facilitate investment decisions for new installations and improve the utilisation of the power system. Synchronous measurement technologies, such as phase measurement units (PMUs), play an important role in this WAMPAC system. This paper presents a method for estimating the power system characteristics related to inertia (M) and damping constant (D) using PMU data.
