. A three-phase filter capable to extract any frequency component (2-500Hz) from the connected CT and/or VT

. Required Frequency to be extracted is entered as a parameter setting

. Relatively long filtering windows are used (setting) in order to achieve good accuracy and frequency resolution

. Required signal is filtered out from all three phases individually

. Values are updated in real time with settable rate of update (e.g. 256ms) SMAI HPAC filter - Output

. Note that filter will deliver the following information after every calculation about the extracted quantity

. Phasor (primary magnitude and the phase angle) at the set frequency is reported

. Estimated Frequency of the phasor is also reported

. When no clear magnitude peak exist in the set pass frequency band the filter will return zero values for the phasor magnitude and angle while the signal frequency will be given value of minus one.

. Up to six such filters can be included in a single 670 IED Speed of Measurement from built-in DR

With such settings new filter output is available every 1024/4=256 samples or 256ms in 50Hz system. Filter gives SSR phasors, but what about Protection?

. Filter is connected further to “standard 50/60Hz” protection functions which then provide pickup and required time delays.

. The following functions from REG670 library can be used

. Over- or under-current protection function

. Over- or under-voltage protection function

. Over- or under-power protection function

. Over- or under-frequency protection function

. Multi-purpose protection function

. Measurement functions: SSR I, U & F values can be shown on built-in HMI or send to any control system via several communication links

. SSR quantities can also be recorded by internal DR in the IED (over limited period of time e.g. 10s at the time) Standard IED Configuration for 50Hz OC protection

. “Swedish SSR experience”:

. Use SSR sub- & super-synchronous voltages at generator terminals

. Use SSR sub-synchronous current in the transmission network SSR Panel for NPP F3

1) For SSR protection use 670 IED Version 2.0 or latter

2) MicroSCADA Hystorian used for logging of all relevant SSR data and other generator measurements onto a PC hard disc. More than one year of data can be stored. Data stored once every 2s. Data logged over IEC61850. Trending feature is available. One of REG670 displays in F3 Possible Applications of the Filter

. Sub-synchronous resonance protection for turbo generators

. Sub-synchronous protection for wind turbines / wind farms

. Detection of SS oscillation between HVDC links and synch. generator

. Detection of presence of GIC (geomagnetic induced currents)

. Sensitive open phase detection for NPP

. Overcurrent or overvoltage protection at specific frequency harmonics, sub- harmonics, inter harmonics

. Presence of special railway frequencies (e.g. 16.7Hz or 25Hz) in the three-phase power system

. Sensitive reverse power protection

. Rotor Vibration

. Shaft over-current protection (MSc thesis work during Q1 2015 )
