Precise time provider with speed optimal phase-locked loop for digital substations of smart grid systems

摘要

Nowdays, the problem of forming accurate time stamps for the continuous monitoring of the stability of the parameters of the equipment of digital substations of smart power systems with real-time scale and, as a result, increasing energy efficiency, aimed at researching the improvement of the quality of time transmission systems using IP technologies and optimization on the speed of phase-locked loop systems used in the time stamp provider. The use of an adaptive digital phase discriminator (DPD) allows you to control the shape of the optimized PLL device's performance.
