Description
Unit protection must quickly detect a fault and react to it, to prevent a severe accident, a prolonged outage or incorrect synchronization of the generator with the grid. According to the company's assessment, many installed protection systems no longer meet current requirements, and maintaining them is increasingly difficult. For such plants the company offers replacement of the whole system, not of individual terminals.
Replacement of unit protection and grid protection is carried out together with the generator synchronization system, and all functions are matched to each other at the factory. The system comprises three parts. Unit protection monitors the generator and the unit transformer. Grid protection works on the side of the connection to the power system and uses the distance principle and other methods that meet the highest requirements for operating accuracy. The synchronization system controls the closing of the generator onto parallel operation with the grid, and an error at this stage can damage the machine.
The hardware is dedicated, with a redundant configuration and diverse-mode measurement channels. Diverse channels reduce the risk that a single failure will lead to a false operation or a failure of protection. The solution meets current grid code requirements. The system supports several communication protocols, has modular hardware, a simple connection scheme and flexible signal allocation. Setup and operation do not require complex procedures, so plant personnel quickly master the system.
The company supports the system throughout its service life, from design and commissioning to service in operation. Terminal types and the full list of protection functions are not given in the available materials; they are determined by the project of the specific unit, taking into account the power evacuation scheme and the requirements of the system operator. The scope of the system for a specific plant is clarified on request, after a survey of the existing equipment and scheme.
Applications include modernization of relay protection and synchronization systems at thermal, gas turbine, combined cycle and hydroelectric power plants. The system is also suitable when generators are replaced, when protection and synchronization have to be reconfigured for the new machine in any case. It is also considered when a plant moves to new grid code requirements that the old protection no longer meets.
