With the increase in technological advances of the smart grid, distribution systems have undergone a great change the same as transmission systems: new technology, different types of load, demand response supporting facilities, large quantities of distributed power interconnection to the distribution network. Meanwhile, the capacity of the distribution network, that is, the number of component an size of investment is considerable, even more than transmission grid. Power measurement plays an important role in distribution networks, including income measurement, voltage amplitude measurement for capacitor switching, distribution feeder current measurements, system device protection measurement. As the next point of setup in smart grid, PMU is necessary for components control, fault detection and control, energy management in the distribution network and increasing reliability and power quality. With technological revolution in Solar and Wind farms, energy can be generated at the destination of consumptions. Use of energy storage devices like batteries has also gone up. To use the existing system effectively, the Bidirectional flow of power takes place. This bi-directional flow can cause trip off, causing frequency or voltage problems. The electrical behavior load is changing.The design of distribution is radial so more monitoring/measurements points are required. The traditional monitoring at a lower revenue per circuit mile like that of transmission cannot be used to monitor the complex distribution system. With the increase in the radial system, the number of measuring instruments goes up, causing high monitoring costs and larger manpower. At such times, micro PMU can be installed. These micro PMU will monitor and measure data in real time system and communicate with PDCs using GPS signals. The developed PMU offers a wide variety of monitoring options like using web enable browsers and hand-held android or iOS devices.
