SynchroGuard increases grid efficiency and reliability by providing real-time visibility of the grid status, enabling safe integration of renewable energies and electric vehicles, and quickly reacting to electrical faults to minimize the impact of power outages. It consists of distributed sensors that measure the so-called "synchrophasors" and a central grid controller that collects all the measurements and performs real-time grid monitoring, automatic control of renewable energy generators, and smart fault management. In addition, we guarantee the simplest installation on the market, because we avoid the use of voltage sensors and we only use clamp-on current sensors, which are simple to install, cheap, and non-invasive. Synchrophasors are very frequent and time-synchronized measurements of voltage and electric current, which enable several benefits. Indeed, compared to competing solutions, SynchroGuard uses 3 times fewer devices on average, is capable of locating 4 times more faults, and enables non-invasive, cheaper and quicker installation. Our invention is protected by 2 pending patents consisting of the first synchrophasor estimation algorithm compliant with measurement and protection accuracy classes, and a very accurate and reliable fault location method.
