ELECTRIC POWER MANAGEMENT

The SUPPRESS group (Supervision, Control and Automation) has developed a model for the Electric Power Management of the University of León, which allows graphically analyzing consumption for any time period. The monitoring and control network of the electrical consumption at the University of Leon comprises equipment from different manufacturers that coexist on the same network. This network uses two communication protocols: Modbus and TCP/IP. The types of equipment installed in this network are:

• Electrical Meters: They are focused on billing, and obtain measurements of Voltage, Current, Power, Frequency, Power, THD, etc.
• Network Analyzers: They are quality control equipments for electricity that measure a greater range of variables. Some of these measurements are: Frequency fluctuations, Voltage fluctuations (slow), Voltage fluctuations (fast), Blink (flicker), Supply Voltage Unbalance, Harmonic Magnitude, Voltage Collapses (DIPs), Voltage interruptions (Short Term), Voltage interruptions (long), etc.
• Modbus-TCP/IP gateways: They provide access to Modbus networks from TCP / IP. These may be included within network analyzers and meters, or be external to them.

The SUPPRESS Research Group (Supervision, Control and Automation) of the University of León designed, developed and implemented this system.
