Software-Defined Electricity Automatically Balances Phases in AC Power Networks

(For the most recent article with updated images click here)


The Software-Defined Electricity method controls and balances power flow in Real-Time by using an innovation in computing and power electronics and an advancement in sensing and controls. The balance across phases is a critical component to power quality in power networks. When there is an imbalance on the phases, there is direct loss in the power network, inducing upstream eddy currents in the transformer on the supply side and neutral current loss on the load side.


It is always important to remember that the loss and instability that occurs from imbalanced phases is always fluctuating. Each phase is loaded with independent machines drawing power from the grid without any feedback on that process, so the imbalance fluctuates according to the random pattern of load energy consumption.


Embedding Software-Defined Electricity into the power network accounts for this, drawing the power equally from the upstream phases and perfectly balancing the transformer, and redistributes the power onto each phase perfectly according to demand on site at the panel. The balance adjustments occur each microsecond, to account for any adjustment in the power consumption by the loads.


Real Time Interaction With Electricity


Our methodology allows for real time data acquisition, analysis, correction, and phase balancing simultaneously. The system is designed to be non-intrusive and perfectly balance the network for a completely optimized electrical environment. This includes the upstream phases and infrastructure along with allowing precision distribution of clean electricity to the entire network.


By automatically balancing the phases, correcting the reactive power and harmonics as the power flows with Software-Defined Electricity, facility electrical networks prevent internal electrical disturbances through in a dynamic and flexible way. This elasticity prevents the tripping of protections devices and protects all connected loads during power disturbance events. Whether the electrical network is in a facility or in a microgrid, Software-Defined Electricity maximizes uptime and efficiency while decreasing costs and maintenance every microsecond.


Dynamic software controlled management of electricity with full data and verification is essential for any operation. Contact 3DFS to learn more.

    This software based automatic phase balancing methodology, employing digital has great benefits, in Industrial Electric Power Systems and Networks based applications.

    It is directly applicable in to-day’s Smart Wires and Smart Grid Technologies, on HV Power lines and Power Systems at Transmission Power levels. Ex. 132kV, 220kV levels etc.,

    wow this would do wonders with radar

    Is it at all possible to automate a 3 phase load balancing… I am running a garment stitching factory where all single phase stitching machines are installed equally to balance th load on each phase but due to irregular attendance of the workers and singlw phase airconditions the remains unbalanced. Sometimes the difference is too it really possible to automate the load balancing… ??? Pls. Advise….

    is there a model adapted to european voltages 230/400 volts ?

    ty, have a nice day.

    Is this equipment suitable to use and available for home users?

    have been following this process a while and anxious for residential application in my off grid residence when using backup power and for extended storage.

    Explain your theory on the process to balance between phases and clear up the sign waves. What KVA units will be available for applications? What kind of paybacks are expected for industrial applications?

    Good web site! I truly love how it is simple on my eyes and the data are well written. I am wondering how I could be notified whenever a new post has been made. I have subscribed to your RSS which must do the trick! Have a nice day!

    Is it at all possible to automate a 3 phase load balancing with high current?
    What the limit de load?

    This seems to be a good product to scale up for placement at distiubution substations…69kV, 138 kV, etc.

    Can you build something on that scale?

    Where does the imbalance “go”? Are we talking a complete re-construction of the wave form at 480kHz?
