Power system reliability enhancement considering smart monitoring
With improvements in smart sensing and digital instrumentation technologies, small, low-cost sensors have been installed in power networks, thus providing new opportunities for smart monitoring. Smart monitoring consists of analog/digital sensors, measurement units, control devices, and protective relays inside a digital communication network working together to gather local information about the power grid, to be recorded in the servers and to demonstrate human machine interfaces (HMI). To keep a power system operating reliably, it is necessary to continuously monitor and indicate crucial points of the power network. This paper introduces various aspects of power system monitoring and indication and proposes a mathematic model to numerically assess the positive effects of smart monitoring on the power system's reliability. Based on the Markov model, the formulation used to calculate the updated failure and repair rates of the power equipment is extracted.
