Services
Stability monitoring and power system studies
Power system engineering for transmission operators, utilities, developers and the consultancies that serve them, delivered in the tools our clients already use.
Monitoring
Stability monitoring in the control centre
Our patented indices, taken from a published method to a screen an operator watches. The work runs from the measurement interface to the operator’s display and the support that follows.
How the indices work- Real-time NLI computed from PMU data streamed over IEEE C37.118, and the relay-based RLI
- Integration with the EMS and wide-area monitoring systems already in the control centre
- Operator training and support after delivery
- Maintenance of the databases behind the application, so past events can be analysed
Studies
Power system studies
Steady-state and dynamic analysis for new connections, for planning and for day-to-day operation.
Connection
Grid connection and compliance
Load flow, short-circuit and reactive capability studies for renewable plant, large industrial loads and HVDC links, and assessment of each against the transmission operator’s grid code.
Dynamics
RMS and EMT studies
Fault ride-through, voltage, frequency and small-signal stability, and the behaviour of converter-connected plant in weak grids, in positive-sequence and electromagnetic-transient detail.
Optimisation
Optimal power flow
OPF formulations for dispatch, reactive power and voltage support, N-1 security and transfer capacity, built around the operating or planning question at hand.
Voltage stability
Stability limits and margins
PV and QV analysis, long-term quasi-steady-state simulation with WPSTAB, and the design of emergency controls and load shedding against voltage collapse.
