We provide complex services in the area of projecting the systems of power devices protection. We project protection connections to protected devices, produced by our company as well as by other companies. We also carry out projects for reconstruction.
COMPREHENSIVE PROTECTION RELAYS PROJECTS
Projects are processed to the extent our customer requests and they can contain:
|overview and block diagrams|
|diagrams concerning inner connection of boxes and switchboards|
|diagrams concerning outconnections|
|table concerning protection relays effect|
|short circuit calculations|
|protection relays parameters adjustment|
For each assembly unit we process single-pole, linear and connection diagrams and other overviews and descriptions that are a standard part of operational designs.
We can elaborate only certain parts of a project individually if a customer requests so. For example, the most frequent orders we accept concern separate calculation of the protection relay adjustment.
SHORT CIRCUIT CALCULATIONS AND ADJUSTMENT OF PROTECTION RELAYS PARAMETERS
A part of the project can be the following:
|specification of protection relays and optimization of their|
|short circuit calculations made using the method of|
|symmetrical components in different short circuit points and|
|types (three-pole, two-pole, ground and single-pole)|
|and for various configurations of the power system|
|overview of calculated values|
|overview of protection relays setting|
|So far we have carried out the calculations of protection relays setting for
generators with the total capacity 5583 MW i.e. sum corresponding roughly
to one third of the Czech Republic installed capacity.
