Applications
The VAMP 210 generator protection relay comprises all the
essential protection functions needed for a generator, except
the differential protection function.
Thanks to the comprehensive range of protection functions the
generator protection relay can be used as the main protection
for a variety of generators from small diesel power plants to
large hydro power plants in the power range from 1 to 100 MW.
Especially versatile and flexible protection functions are
provided for the generator earth-fault protection. These
features are needed, when for instance, several generators are
connected in parallel to the same busbar but their earthing
principles differ.
The other energizing connections, except for the ones for the
earth-fault protection, are independent of the generator size
and type. For large generator a higher accuracy of the
protection functions is needed. Being based on numerical signal
processing and high-resolution A/D conversion the VAMP 210
generator protection relay fulfils also these requirements.
The three generator protection applications on the following
pages illustrate how the flexibility of the VAMP 210 generator
protection relay can be utilized.
