6 FAQs about [Relay protection acceptance of energy storage power station]
Why do we need protective relays?
The selection and applications of protective relays and their associated schemes shall achieve reliability, security, speed and properly coordinated. Meanwhile, protective devices have also gone through significant advancements from the electromechanical devices to the multifunctional, numerical devices of present day.
What is a protection relay?
(protective relaying) The maximum distance from the relay location to a fault for which a particular relay will operate. The reach may be stated in terms of miles, primary (of a relay) The extent of the protection afforded by a relay in terms of the impedance or circuit length as measured from the relay location.
Why are new relay protection algorithms necessary?
New relay protection algorithms have become necessary because of the special features of microgrid regimes with distributed power generation sources. The a
Why are the relay protection settings too coarsened?
This approach leads to excessive coarsening of the relay protection settings and, in some cases, to their incorrect behavior, which is confirmed by the publicly available accident rate statistics. The methodology for setting the relay protection using mathematical models of EPS and relay protection is formulated. Features of this approach:
What is the best solution for relay protection models?
In addition, it is obvious that the solution of more complex relay protection models, for example, with higher-order filters, transformerless auxiliary converters, etc., by software systems will be very resource-intensive, therefore, the software and hardware solution of mathematical relay protection models seems to be the most promising.
How are relay settings determined?
Relays settings are determined in the process of modeling modes in the aggregate model “EPS-RP”. For each protection of each EPS facility, a list of modes is forms, consisting of two parts: 1) modes for settings determination; 2) testing modes. The first group includes all modes in which the protection should not work.
