关于客户
Oracle Corporation is a software giant based in Redwood Shores, California. It is the world’s leading supplier of information management software, with its products operating in everything from personal digital assistants to global information networks. The company has thousands of software developers and provides non-stop, 24-hour-a-day technical support to its customers. Power interruptions can be extremely costly for Oracle, potentially resulting in losses of 5 to 10 million dollars per day in sales and productivity. The company's customers, many of whom have mission-critical support needs, are also significantly affected by power interruptions. Oracle's need for reliable power was the driving force behind setting up its own substation, a 13 MW electrical distribution system, and a power management system.
挑战
Oracle Corporation, a leading supplier of information management software, required a reliable power system for its thousands of software developers and customers that depend on non-stop, 24-hour-a-day technical support. Power interruptions could result in significant losses in sales and productivity, as well as affecting customers with mission-critical support needs. Oracle's need for reliable power was the driving force behind setting up its own substation, a 13 MW electrical distribution system, and a power management system. The company initially considered purchasing electricity from the local utility at primary voltage, 12 kV, also known as voltage buy-up. However, the utility feeder to Oracle would still be shared with residential and other non-industrial loads, and they would be subjected to several outages per year. Instead, Oracle decided to intercept the 60 kV circuit from the utility’s transmission line that passes over the Oracle campus. Since the 60 kV circuit’s unplanned outage rate proved to be more reliable, at less than one event per five years, and payback was favorable, Oracle’s board of directors approved the project and construction began.
解决方案
Oracle Corporation implemented a power distribution strategy with the help of Schneider Electric. The solution involved deploying a full-featured power management system, including EcoStruxure™ Power Monitoring Expert and PowerLogic advanced power meters. The power management system was installed at the substation and at the transformer of each critical building, directly connected to the corporate Ethernet network by 10BaseT and 10BaseFL links. Desktop access to power system data is available via EcoStruxure™ Power Monitoring Expert. The system is used for monitoring harmonics, transients, waveforms, sags/swells, and other disruptions, tracking energy use, peak demand, time of use, and power factor, automatically reading meters, paging facility personnel during alarms, and reading temperatures, pressures, and oil levels in main and secondary transformers. The metering and reporting system has helped the company identify sources of, and corrective actions for, many potentially damaging disturbances.
运营影响
  • The power management system has helped Oracle identify sources of, and corrective actions for, many potentially damaging disturbances.
  • The system provides real-time control and monitoring, allowing Oracle to monitor critical power aspects of the campus itself, without depending on the local utility for information or a consultant to diagnose a problem.
  • The system has proven its value to Oracle, with more savings being realized by identifying areas of high energy usage, improving energy efficiencies, and auditing utility bills.
  • The system offers growth potential to monitor additional off-site locations and provides access for multiple simultaneous users.
数量效益
  • In one year, the system measured more than 30 utility-side transient events.
  • The project had a return on investment (ROI) of three years.
  • Continuous savings made by identifying areas of high energy usage, improving energy efficiency, and auditing utility bills.
