As the installed capacity in decentralized sources of energy continues to increase, the distribution system can become less stable resulting in a fluctuation of grid parameters such as voltage and frequency. To keep the equilibrium and ensure safe operation of the grid, mains protection is essential for every power source operating in parallel to grid.
As a result, Utilities and Distribution Network Operators (DNOs) issue regulations, which every site generating power must comply with. These regulations highlight the need for protection relays in order to protect the distribution network from dangerous effect of asynchronous generation and minimises the likelihood of equipment damage caused by disturbances coming directly from the mains network.
ComAp deliver a family of mains protection modules that provide the necessary protection functions to meet the requirements of all applications where generators operate in parallel with the mains.
