Applitech Power-IT is a Power Management System (PMS) that interacts with the existing power grid to strengthen outage management, load shedding, and forward and reverse synchronization. It serves as the backbone for business planning, performance reporting, and decision support around generation and distribution.
Overview
Power-IT performs the classical tasks of distribution network monitoring and control while executing operational functions like feeder automation, system restoration, loss minimization, and optimal feeder recognition. The result is a measurable lift in operational efficiency and service quality, delivered on a modern, modular architecture.
Objectives

Load shedding and grid islanding
Load shedding uses a frequency-based, tiered scheme. The system monitors bus frequency at each meter; when frequency drops below a configured threshold the associated non-critical loads are shed under operator-configurable rules. Restoration is manual after safe conditions return. Grid islanding is implemented at the substation using a protection relay that opens on frequency excursion or detected fault, isolating the facility from the upstream grid.
Synchronization, generator modulation, and balance of plant
Power-IT can drive automatic forward and reverse synchronization. Where generators accept setpoints over RS-485, the SCADA modulates the generator frequency to match the external source and closes the synchronization relay once within tolerance, all behind a single operator action. Generator setpoints are continuously modulated to keep a positive potential between plant demand and on-site supply, preventing reverse power flow to the grid. Energy meters at incomers and major plant sections compute a balance of plant, exposing distribution losses and enabling cost allocation across plant areas.
Operator interface
Workstations equipped with VDUs, keyboards, and cursor devices give operators a consistent, intuitive graphical interface for real-time monitoring, control, alarm acknowledgment, and operational reporting. Auxiliary printers, digital displays, and projection screens extend the interaction model into the control room and beyond.
