Inputs
Data from Utilities and MV Gensets
The following data is required:
-
Electrical measurements: power sources and feeders are monitored to process real-time protection algorithms and automation schemes to automatically operate actuators in case of electrical fault. Incoming (from utilities) and generated (from genset) power data is collected in real time and shared across an IEC 61850 network to execute load-shedding and load-restore automation schemes.
-
Status and diagnostic information: if any source or network control operations involve the utility incomers, MV secondary substations, or gensets in the facility, it is essential to determine their status and to access diagnostic information to run proper automatic reconfiguration sequences.
For the utility incomer and for the genset(s), these measurements are collected by protection relays (such as the PowerLogic P5/P3), automation controllers (such as PowerLogic C5), or EcoStruxure Power Automation System Gateway (EPAS-GTW) in the case of Modbus devices.
Data from MV Loop Topology
The following data is acquired from protection relays with embedded metering (PowerLogic P5/P3) and from automation controllers (PowerLogic C5) for automatic systems and helps operators decide on the best supply path through the electrical distribution network:
-
Electrical measurements: measurements such as voltage, current, and power are collected to process real-time protection algorithms and automation schemes for power restoration, load shedding, etc.
-
Status and diagnostic information:
-
Status and diagnostics from contactors, switches, and circuit breakers
-
Trip signals from protection relays
-
Operation mode of automation schemes (local/remote, manual/auto, test)
-
Status and diagnostics from protection relays and/or automation controllers
-
Data from MV Secondary Substation Loads
In critical facilities, the preservation of essential loads such as motors, machines, or other equipment is of utmost importance. Therefore, the following data is key:
-
Electrical measurements: consumed power data is collected in real-time and shared across the IEC 61850 high-performance Ethernet network to execute load-shedding and load-restore automation schemes.
-
Status and diagnostic information are necessary to understand the conditions of these essential loads prior to shedding or restoring them.
This data can be collected from automation controllers (PowerLogic C5), through digital and analog inputs connected to MV secondary circuits, or through EcoStruxure Power Automation System Gateway in case of Modbus devices.
User Controls
In the event the protection or automation system halts due to improper operating conditions or for the purpose of maintenance, the user is able to issue external control actions such as resetting of controls or open/close orders either:
-
from a Central HMI (EcoStruxure Power Operation) or
-
from the front panel of local devices (PowerLogic P5/P3 or C5).
