        成功案例: 水处理

        Anonymous (Hungary)

        成功案例: 水处理 15%  energy savings, ROI in less than 3 years

         

        I. CUSTOMER ENVIRONMENT / PROJECT CONTEXT

         

        Customer profile:

        • Bacviz is the operation company in charge of providing drinking water to the town and region of Kecskemet. It represents a population of 120 000 inhabitants.
         

        Customer objective and constraints:

        • In Hungary the electrical utility providing electrical energy to the water operation company has a price policy based on a fixed subscription. When the water utility has peak demands over the subscription value some penalties are applied. The water utility, want to avoid this cost.
        • More generally a clear understanding of the consumption of the different process steps is required to optimize the process. On average electricity bill represents up to 30% of operation cost for a water utility.
         

        II. SOLUTION IMPLEMENTATION

         

        Implementation methodology (main phases):

        1. Meeting with operators to understand the key step of its process : deep underground pumping, sand filters, chlorination.
        2. Instrumentation of the electrical network of the customer with measurement devices connected to a web server.
        3. Analysis of the data collected by the Schneider Electric services team.
        4. Creation of an official report on a regular basis and presentation of the conclusions to the operation company staff.
         

        Duration:

        • 2 years: 2004 to 2006
         

        Solution overview (services, products, systems, architectures...) :

         
        Solution overview (services, products, systems, architectures...) :1. Revamping of Low Voltage switchgear
        2. Compact NS Micrologic electronic trip units
        3. Powerlogic meters and control
        4. Modbus/Ethernet communication units
        5. Ethernet server information collection
        6. Information analysis
         

        How did we estimate the energy savings (methodology, tools, ...)

        • Energy savings have been directly obtained by the reduction of the contract from a 600kW base to a 400kW base (winter subscription)
         

        III. RESULTS / ACHIEVEMENT

         

        Customer benefits:

        • The customer has a lower contract with the water utility.
        • He is able to manage the process to avoid peak demand : no filters backwashing during deep water pumping for instance.
        • Balancing of the pumps to limit ageing.
        • Pulsed air compressor optimisation.
         

        Customer testimonies (Verbatim):

        • Plant operation manager: "After 6 months of operation and the two first monitoring reports we have optimized the energy cost . We wish to extend the complete supervision of our electrical equipment on 2 pumping stations at Kecskemet."
         

        Schneider Electric differentiating values VS competitors:

        • Local service team collaboration with a local panel builder.
        • Full solution proposed by the same team including electrical equipment revamping, Ethernet TCP/IP transmission of data via a safe router, interpretation of data by experts, quarterly reports for recommendations.
