The HUNTER is the newest addition in Survalent Technology’s innovative Station Controller family of intelligent control devices. Ideally suited for Substation Automation, the HUNTER has 12 direct AC input channels.

The HUNTER uses the raw voltage and current inputs to measure and calculate the most common electrical parameters such as; Voltage, Current, Watts, VARs, Power Factor, Frequency, Watt hours, etc.

Remote Power Quality Monitoring with Oscillography is also a valuable feature of the HUNTER. Power Quality is accurately measured with 11 bit resolution (plus sign) and 32 samples per cycle.

Power Quality measurements include:

• Total Harmonic Distortion in Voltage THD (V)
• Total Harmonic Distortion in Current THD (I)
• Harmonic Spectrum up to the 15th harmonic

Event Triggered Oscillography for all analog input AC channels may be triggered by:

• Fault Current
• Harmonic Distortion (Voltage and/or Current)
• Sag
• Swell

STC guarantees support and availability of its Station Controllers for at least 10 years

Station Explorer is a PC-based windows program used to map both RTU hardware points and IED database points directly to master station database points. It combines map editing, compiling and downloading tools into one package, and consists of the following major functional parts:

• A ‘Hardware Point Map Editor’, which is used to edit HUNTER RTU hardware point maps.
• An ‘IED Configuration Wizard’, which guides the user to go through all necessary configuration procedures so that all necessary data is entered correctly.
• A ‘Point Map Compiler’, which compiles the point maps produced by ‘IED Configuration Wizard’, checks and reports any errors, packs the data in a predetermined format and save the binary map files onto disks.
• An ‘IED Database Editor’, which is used to input and manage the databases of different IEDs of different protocols made by different manufacturers.
• A ‘File Download Tool’, which is used to download the binary point maps produced by the ‘Point Map Compiler’ onto the RTU.

The database of the Station Explorer contains all the information of an IED that is required to request data points from the IED and on the format of the received data. This information is used when the IED is configured.

As an example in MODBUS, points can be retrieved using different function codes and although there are some standards for using the function codes, each manufacturer may use them differently and still comply with MODBUS. The data being returned can have many formats (signed or unsigned 16 bit value; signed or unsigned 32 bit values in two registers, etc) This information is set up once in the data base, and when it comes time to select points from the IED, the user does not have to worry about these details. In fact it is expected that the user will not have to consult the manual for the IED during this process.

Extensive metering capabilities allow the HUNTER to calculate:

• Amps (I)
• Volts (V)
• Watts (W)
• Volt-Amperes Reactive (var)
• Volt-Ampere (VA)
• Power Factor (PF)
• Hertz (Hz)
• Watthour (Wh)
• Volt-Amperes Reactive Hour (varh)
• Total Harmonic Distortion Volts (THD V)
• Total Harmonic Distortion Amps (THD I)
• Harmonic Spectrum (though 15th)

The HUNTER includes a Power Quality application that allows the user to setup Oscillography capture triggers for each AC input.  The triggers can be set for: current fault, voltage sag, voltage swell, and harmonic distortions.

Each event can be downloaded and viewed in the power quality oscillography display.
