The Transmission Network Applications (TNA) suite provides tools for advanced monitoring beyond SCADA in order to assess the security of the transmission grid against planned and unplanned outages and varying system conditions. TNA will inform the operator of the current system state, potentially harmful events to monitor and make recommendations for action to take in response. The application proactively prevents system degradation and thus lowers the cost of operation.
With its Orthogonal State Estimator, Spectrum Power represents a technological breakthrough. It meets the need for state estimation that combines the speed of a conventional design with the ruggedness of orthogonal transformation techniques.
Network Parameter Adaptation (NPA) provides parameters used to generate a forecast of bus loads, regulated bus voltages and the status of time-switched breakers. In real-time execution, the State Estimator uses the parameters to schedule loads and desired voltages at all unobservable buses and to generate pseudo load measurements. In study situations, the Power Flow function uses these parameters to schedule bus loads and desired voltages for the specified day and hour of a study.
This application provides a reliable way of determining the security of a power system under specified contingencies. For each contingency, Security Analysis simulates the steady-state power flow solution and checks the network for out-of-range conditions.
Security Analysis also observes planned outages that are scheduled for the immediate future (Look-Ahead mode) and provides an early warning concerning the potential impact, giving operators time to prepare preventive measures and/or reschedule the outages.
In the case of Spectrum Power, the core function of optimal power flow is fully integrated in the control system, providing a clear, practical interface. It also permits largely automated operational sequences, along with detailed analytical facilities.
