zenon come Sistema di Gestione della Distribuzione (DMS)

Stai cercando una soluzione intelligente per tutte le operazioni di monitoraggio e gestione delle reti energetiche? Se la risposta è sì, zenon è il sistema software adatto al tuo sistema di gestione della distribuzione. Dalla configurazione di progetto e visualizzazione, ai report e all'archiviazione conforme alla legge: zenon offre un'ampia gamma di applicazioni che rendono le operazioni sicure, stabili ed efficienti.

Automazione di sequenze di comando complesse

 

I processi di commutazione complessi richiedono una pianificazione precisa e un'elevata concentrazione durante l'esecuzione. Il Command Sequencer di zenon, il modulo per l'automazione di sequenze di comando, risolve questo problema ed evita potenziali fonti di errori. Puoi usarlo per creare sequenze di comando in un ambiente protetto e poi testarle con una simulazione. L'esecuzione nelle operazioni viene svolta in automatico. In questo modo si evita una commutazione errata e lo spegnimento involontario durante le operazioni reali, aumentando la sicurezza della fornitura.

Perfetta consapevolezza della situazione

 

Una funzione centrale di zenon è la Visualizzazione globale. La rete completa, inclusi tutti i generatori di energia, le apparecchiature di commutazione e le linee sono visualizzate graficamente con una panoramica chiara. Puoi usare la funzione di zoom per passare dalla visualizzazione generale all'ingrandimento desiderato e osservare meglio i dettagli. Le informazioni vengono visualizzate sempre con la precisione dei dettagli necessaria. Puoi avere così una panoramica generale e ottenere le informazioni con il livello di dettaglio di cui hai veramente bisogno.

Passato sotto controllo grazie al Process Recorder integrato

 

Spesso è necessario ricostruire lo stato della rete precedente, ad esempio dopo un problema. Grazie a zenon non avrai bisogno di eseguire laboriose ricerche di risultati e di valori salvati nelle liste. Il Process Recorder ti fa visualezzare la situazione precedente in maniera chiara all'interno della schermata della rete. Lo stato precedente delle apparecchiature di commutazione risulta immediatamente chiaro e può essere analizzato più facilmente. Grazie alla barra temporale navigare nella cronologica è facile. In questo modo puoi analizzare meglio i guasti, dedurre l'orario in cui si è verificato e registrare con maggiore facilità le aree della rete interessate.

Rapida individuazione della posizione del guasto

 

Gli allarmi acustici di zenon avvisano in caso di corto circuito e dispersione verso terra: zenon ricorre a segnali di dispositivi di protezione per individuare la posizione dei guasti o la loro direzione. La visualizzazione della direzione e le misure di impedenza vengono utilizzate per determinare dove è avvenuto il guasto. La posizione del guasto è indicata da linee colorate e aree evidenziate. In questo modo puoi delimitare e individuare la posizione dei guasti più rapidamente, ricorrere al personale tecnico in maniera più efficace e assicurare una fornitura di migliore qualità.

Interfacce utente personalizzate per una migliore esperienza utente

 

zenon gestisce stazioni di controllo impegnate 24 ore al giorno e gestite con operazioni a turni. Ogni operatore ha le sue impostazioni preferite. Il sistema può quindi essere configurato in modo da salvare le ultime impostazioni di ogni utente. Gli operatori possono impostare le proprie preferenze alla fine del turno e visualizzarle nuovamente al successivo. Non c'è bisogno di adattare ogni volta l'interfaccia utente: ogni operatore la visualizza esattamente come al logout del turno precedente.

Full situational awareness

A core function of zenon is the Worldview. Comprehensive network schemes, including all related assets such as generators, pumps, switching equipment and lines are displayed in graphical form and with a clear overview. From there, you can zoom in and out on components in the network at any level of details and gain the insights you need to make an informed decision. In a complementary GIS (geo information system) view, the corresponding infrastructure components can be illustrated in their actual geographic arrangement. Information, such as alarm states or outages can be intuitively augmented. Structured alarm and event data can be selectively displayed to support the operator to stay in control in any situation.

 

Ergonomic operation and topologic features

Operating a critical supply network, like medium voltage distribution grids, requires practical features which allow you to reflect the overall condition of the network in every detail. Switching procedures in zenon are supported by a topological model of the overall grid. This means, any control action which is intended by the operator can be checked upfront for potentially negative consequences. In this way, switching actions which could peril the integrity of the grid, or cause damage to an asset are excluded. zenon can evaluate the supply condition for certain network segments, which helps to plan maintenance in the supplying parts, and to ensure continuous supply for all consumers. Also, specific features are available to identify and lock assets safely which are determined for on-sight maintenance. Network component conditions which cannot be acquired by means of a protocol-based connection can be aligned by means of manual correction commands. For full traceability, all activities are by default logged in a system-wide Sequence of Events protocol. With the so called “Command Sequencer” in zenon, standard switching procedures can be templated and executed on demand. This reduces operational effort but also adds safety, through the usage of proven switching sequences.

Smart algorithms to manage electrical grids

advanced features to determine the actual load state, and to pre-calculate the future load state of the electric equipment. Only then can the nominal load capacities of power lines and connecting elements be optimally used, and congestion states can be avoided. zenon comes with an integrated Load Flow Calculation module to determine the electric currents and voltages as well as the related phase angles for the specific points in the grid. With this, the operator gets a perfect overview on the overall load situation and can intervene in case of imminent congestion. Load values for areas, where no physical measurements are available will be determined by zenon´s State Estimator. The State Estimator allows to approximate the electrical condition of the grid, even if it is strongly underrepresented by real physical measurements.

 

Based on the load flow model, a pre-calculation can be performed while switching actions. In this way it can be ensured that the changed grid configuration after the switching still results in a permissible state, without congestion.

 

Finally, the model also allows zenon to perform a contingency analysis – a so called “N-1 Calculation”. With this, the operator can make sure that the grid will not be congested, even if one asset (cable, line, transformer) fails. All-in-all these features will help the operator to steer the grid infrastructure safely through periods with high power flow or through situations where planned or unplanned grid reconfiguration needs to be performed.

Quick fault location and detailed investigation

To achieve highest availability ratings, utilities need to react fast in case of breakdowns. zenon supports the precise spotting of fault locations, based on values received by the respective distance protection devices. zenon can indicate the actual fault location in the single line diagram and will highlight the network section which is affected by the outage. This will help the operator to immediately prepare for the required switching actions to isolate the fault and quickly restore the power supply to as many consumers as possible. On the other hand, the indication of the fault location in the GIS view informs about the exact geographic location of the outage. This information can be used to dispatch and guide the maintenance crew.

 

Any incident in the supply network can be tracked and investigated in depth, using detailed alarm records and sequence of events lists (SoE) in zenon. Moreover, detailed historic archives and corresponding trends and reports can be easily utilized for such investigations by the operations team. Furthermore, a process replay function in zenon allows for an ex-post assessment of all events which happened during an incident. The investigator can freely rewind and forward event by event during the incident period, or just replay the recorded events in real time mode, while freely switching through the available screens of the HMI solution. Instead of parsing through tons of event list entries the investigator can rely on the exact visual replay of all related procedures.

 

Resilient and secure network architecture for maximum availability

zenon comes with highly robust, yet simple to deploy networking features. Zenon´s flexible multi-server / multi-client architecture allows to modularize the process control and monitoring aspects and distribute them to a respective set of servers. This builds the foundation to realize a diversified, fail-safe topology. On the other hand, side, visualization clients can flexibly – and of course backed by with RBAC (role based access control) – access process information or interact with the system. Hot-standby redundancy is available ‘out-of-the-box’ in zenon and can simply be utilized with just a few mouse clicks. Moreover, zenon can evaluate the health of the system and on demand perform a pre-emptive redundancy switchover or detect weak communication links and change over to better ones. The operator will constantly be informed about any event and will remain in full situational awareness.

 

All zenon functions are also available to work in virtualized environments, which allows for efficient solution deployment and maintenance in conjunction with up-to-date IT management techniques. Finally, networking features and protocols such as IEC 60870-5-104, DNP3 or IEC 61850 support secure authentication and TLS-based encryption according to IEC 62351 in order to achieve a maximum security level.
