Kopsavilkums	Protection relay coordination ensures that when a fault occurs, the relay nearest to the fault operates first, isolating only the faulted section while keeping healthy portions of the network energized. This selective clearing strategy minimizes service disruption and is achieved by carefully coordinating pickup currents and time delays across a series of relays. It is fundamental to reliable power system operation.	Power system state estimation infers the real-time voltage and phase angle at every bus in a power network from redundant measurements of power flows and voltages. It is the foundation of modern grid operations, enabling real-time monitoring, contingency analysis, and optimal control. Advanced state estimation with synchronized phasor measurements (synchrophasors) enables faster control and detection of instabilities.
