What do you do if your power distribution system is underperforming and you're an electrical engineer?

Reliability and availability measurement is one of the main factors in well-performance of the electric distribution network. SAIFI and SAIDI are indices that we consider when we want to know whether our distribution grid supply the consumers with continuous electricity. In this regard, our distribution grid should get monitored. Smart Grid allows system operators better control and measurements via smart devices such as IED’s, SCADA Remote Terminal Units (RTU’s), smart switches, smart meters, renewable energy, energy efficiency, smart appliances.

Absolutely, To address underperformance in a power distribution system, assess the design for flaws or outdated components. Ensure load distribution matches specifications; upgrade if load has increased. Evaluate critical components' condition like transformers and circuit breakers for wear. Pinpointing these factors helps implement targeted solutions.

When your power distribution system isn't pulling its weight, it's time for a systematic assessment. Dive into the nitty-gritty of the system's design, looking for any weak links or outdated parts that could be holding it back. Double-check the load distribution to ensure it's in line with what the system was designed for. If there's been a surge in demand, you might need to beef up the system to handle the extra load. Don't forget to give the transformers, circuit breakers, and other key players a once-over – wear and tear could be causing the hiccup.

First understand, how electrical network behaves when it’s operating under unbalance loads. Only then you will see power system, where things go wrong by change in current vectors to unbalanced power system. In 3-phase unbalanced load, the 3 currents are not equal in magnitude but still separated at 120 degrees. All currents come together through neutral of source as currents vectors merge together, but phases current will NOT cancel out and hence neutral current is NOT ZERO. In an unbalanced healthy system, 3-phase current have different magnitudes and sources still supply only +ive sequence current, but load side contains -ive sequence current that make system unbalanced to underperform & create harmonics too for functional error.
