Dynamic System & Network Performance Monitor (DSM)
DSM performs the important tasks of power system stability supervision and determination and analysis of key system parameters.
- Voltage stability monitoring and steady-state instability supervision
- Generation outage, load rejection and system frequency response analysis
- Primary- and secondary response supervision
- Load-shedding tuning and optimisation
- Power System Stabiliser (PSS) effectiveness supervision
- Tie-line power exchange and network control characteristics
- Control performance supervision and identification
- Generator and load parameter identification
- Phase angle supervision
- Power oscillation detection and analysis
- Subsynchronous oscillation monitoring
- Supervision of super-synchronous control interactions
- Customised signal aggregation based on multiple input signals
Power Plant Monitor
Precise knowledge of grid response and plant characteristics is often required for solving stability problems, operating within stability margins and for the optimal tuning of grid and plant control systems.
- Generator, motor and general feeder load tests as well as parameter identification
- AVR/exciter performance supervision and identification
- Prime mover and associated controls supervision (boiler control, primary control, etc.)
- Optimal tuning of Power System Stabilisers (PSS)
- Supervision of shaft oscillations
Grid Code Compliance
New rules and grid codes for the connection of generators to the grid are emerging worldwide. In every region, the operators responsible for the safety and reliability of the power system have established different requirements for the connection of renewable generation systems to transmission and distribution networks.
- Grid code compliance verification
- Low and High Voltage Ride Through (LVRT/HVRT)
- Verification of generator response during balanced and unbalanced voltage dips/swells
- Verification of voltage support requirements during dips/swells and after clearance
- Supervision of power plant non-disconnection
- Supervision of active and reactive power recovery according to the user-selected grid code
- Assessment of power quality requirements, flicker and harmonic levels according to IEC 61000-4-15, IEC 61000-4-7, IEC 61400-21 or TR3 (specific methods for renewables)
- Support of various grid code definitions including ENTSO-E, FERC, EEGG/TR4, China BG/T, and that used in South Africa
Phasor Measurement Unit (PMU)
Wide area measurement (WAM) in regional transmission grids and very wide area super grids via PMUs is considered to be one of the most important measurement techniques in future power systems. PMUs increase grid reliability by early detection of faults and prevention of power outages.
- Real-time phasor measurement technology with high accuracy synchronised time stamping
- IEEE C37.118 /2005 /2011 compliant
- Multiple C37.118 inputs
- Aggregation of C73.118 inputs with analogue signal inputs
- C37.118 output
Power Quality Monitor
Poor power quality is a problem for all consumers. It contributes to high energy costs and production disturbances.
Following the IEC 61000-4-30 standard it is possible to verify the power quality of the power supply.
- IEC 61000-4-30 Class A
- True RMS voltage and current, frequency, harmonics and interharmonics up to the 50th order according to IEC 61000-4-7, as well as unbalance, voltage dips, swells and interruptions
- Flickermeter according to IEC 61000-4-15
- Recording of all time frames from half-cycle stream up to 2 hours aggregated
- Statistical reports
