What is NTS?
Electrical outages can cause severe disruption to customers and have serious financial consequences as well. Trained dispatcher however, can significantly reduce the time of system restorations and can prevent further escalations.
The Network Training Simulator (NTS) is your 21st century tool to effectively and efficiently train dispatchers and professionals operating and controlling any kind of electrical network. It is also useful for the practical training of university students specializing in electrical engineering.
- transmission NTS for transmission system operators (TSO-s)
- distribution NTS for electrical energy providers (DSO-s)
- electrical auxiliary NTS for nuclear power plants (NPP-s)
- traction power NTS for railway companies
- Realistic and graphical user interfaces (GUI): The trainee’s GUI is the user interface of the SCADA, which is a replica of the on-line SCADA system. Thus the trainee can practise on the same GUI which is used in every-day work, while trainers can supervise and control the operation of the NTS with the help of manageable schema pictures.
- Time machine: Trainers can set simulation time and speed up or slow down the passage of time. Thus quick events can be demonstrated, while longer, uneventful periods can be passed over.
- Archive system: Trainers can save all changes of digital signals and analog measurements. These archived events can be replayed for didactic purposes.
- Programming events and conditional events: Trainers can compose scenarios based on the events of the network or create events triggered by other events and conditions.
- Time schedules: Changes in the amount of electrical energy produced and consumed can by modelled with the help of time schedules (time schedules, profiles).
- Realistic power flow and voltage profile: The realistic picture of power flows and voltages is provided by the built-in fast load-flow calculation.
- Discrete device modelling: The NTS models the network as a system of interconnected single devices (protections, automatics, switchgears, measure transformers etc.). The network-events are produced with the cooperation of the modelled devices.
- Interlocking system: The traditional logical interlocking system and the interlocking system based on comprehensive topology analysis hinder an erroneous switching operation that trainers can disable. In case of an erroneous switching operation initiated by the trainee, the short circuit will be cleared by the protection system.
Universal, it can be connected to any kind of SCADA system
- Standardised SCADA connection: The NTS communicates with the data transfer protocols widespread in power industry (SAM, IEC870 101 and 104), so it can be connected to any kind of SCADA system.
- Real-time operation: The NTS provides the timestamps of signals from electrical devices (e.g. signals of protection or circuit breaker) with 1 msec resolution.
- Scalable network model: The NTS can simulate both a single micro-grid and the whole transmission and distribution network of a country too.
