Vista Characteristics

Vista comprises nine integrated modules, operating under Windows 95/98/NT/2000/Xp, uses robust database technologies and a sophisticated Windows user interface. The primary functionalities are as follows.

·        Long-term generation scheduling (LT Vista) over several years, using user-defined periods of approximately one week or more

·        Short-term generation scheduling (ST Vista) over the next one to two weeks, in hourly timesteps (or user-defined multiples of one-hour)

·        Hosting of all data (Data Vista)

·        Monitoring of real-time data, including SCADA, hydromet stations and internal corporate processes (eg) price forecasts, load forecasts, etc. This is carried out in RT Data Vista

·        Inflow forecasting in the short-term (deterministic, hourly, for 2 week period) and in the long-term (probabilistic extended streamflow prediction, ESP). This is undertaken in Inflow Vista

·        Definition and processing of price forecasts, and opportunities to buy and sell power (Xchange Vista)

·        Definition and processing of load forecasts and/or committed transactions (Load Vista)

·        Production of standard and user-defined reports (Report Vista), useful for compliance monitoring

·        Off-line analysis or post-audit, which is a “control room simulator” over many years of varying conditions (AUTO Vista). This module is very powerful for strategic planning, relicensing studies or facility upgrade studies

Vista develops economically optimum generation schedules, taking account of the following.

·        Detailed hydrologic analysis (cascade network flow, lag/route in channels, inflow forecasts, flood handling)

·        Detailed hydroelectric analysis (hydro and PGS facility definitions, over 100 operations constraint types)

·        Market conditions

·        HV transmission limitations (inter-area line limits and losses)

·        Reserve requirements

·        External energy sources (wind, run-of-river, etc)

·        Thermal facilities if applicable

We also provide an information technology (IT) service to enhance your legacy software applications, and to link them with Vista.
