The document discusses configuration of a Micom P-632 relay. It describes the protections available in the relay like differential, restricted earth fault, etc. It provides details of the input parameters required and steps to configure the relay which includes setting date and time, system specifications, selecting protection blocks, output relay configuration, LED configuration, and settings of protections. The configuration is done by taking the relay offline, enabling the required protections and setting their parameters.

Excitation System & capability curve of synchronous generatorMANOJ KUMAR MAHARANA
Excitation systems perform control and protective functions essential to the satisfactory performance of the power system.
The amount of continuous reactive power a generator can supply is restricted by various limits. In the over-excitation region limits are imposed by rotor heating or amount of field current and second is the stator current. In the under excitation region the limits are imposed by load angle. So in steady state the generator should always operate within this region and the loci of the various limiters are called the capability curve of the generator.
Autorecloser relays are widely implemented in the electric utilities Over Head Lines networks to improve power availability and to maintain system stability.
Site testing need to be performed before operation to ensure proper function of Autoreclosers.

Phasor Measurement Units (PMUs) make a valuable contribution to the dynamic monitoring of transient processes in energy supply systems. The advantage over standard RMS values is for one thing that the phasor values of current and voltage are transmitted. Secondly, each measured value includes the exact time stamp and therefore should be assigned within the transmission path in which it originates independent of the time delay. The phasors and analog values are transmitted by the PMU with a configurable repetition rate (reporting rate). Due to the high-precision time synchronization (via GPS), the measured values from different substations that are far removed from each other are compared, and conclusions about the system state and dynamic events, such as power fluctuations, are drawn from the phase angles and dynamic curves. The PMU function transmits its data via an integrated Ethernet module using a standardized protocol IEEE C37.118. The evaluation can be done with a Wide Area Monitoring System e.g, with SIGUARD PDP (Phasor Data Processor).
1.2 Definition
A Phasor Measurement Unit (PMU) measures the phasor values of current and voltage, as well as the values of power frequency and rate of change of frequency (ROCOF). This data will be combined with high precision time stamp.
The measured data are transmitted to a central analysis station (Phasor Data Concentrator, PDC) in accordance to the standardized transmission protocol IEEEC 37.118.
A PMU can be a stand-alone physical unit or a functional unit within another physical unit.
Total Vector Error (TVE)
The TVE describes the error between the actual and the measured values of the input signal of the PMU device.
