Abstract This paper takes a 110kV system as the protected object and equip relay protection for it and set protection parameters.These protections include the 10kV line''s overcurrent protection with
To sum up, the presented approach integrates Independent Factor Evaluation (IFE) and quantum genetic optimization (QGO), providing a comprehensive solution for optimizing relay
To improve the reliability and sensitivity of multi-level relay protection in distribution networks with distributed power sources, this study designs an adaptive setting strategy optimization method.
Firstly, the impact of the access of a large number of distributed generations on relay protection in the distribution network is analyzed. Then, considering the requirements of relay protection for quickness
In the calculation of relay protection settings, the current speed protection is usually calculated using the short-circuit current in the maximum operating mode, so it
Fingrid''s application guideline for relay protection presents the operating principles of the relay protection in Fingrid''s 110, 220 and 400 kV power networks and the requirements for operation of the protection
In this paper, the main electric wiring mode of 110kV substation is selected, the structure of substation is determined, and then the main wiring diagram is drawn.
The conventional distribution network relay protection setting planning is generally fixed-point or distribution network target optimization, which is relativel
This paper proposes two solutions: first, analyzing from the perspective of relay protection strategies, adjusting the settings and operation modes of protection devices; second, optimizing the
