Protection Coordination of Obsolete Protective Devices

One of the essential studies in Electrical Design Analysis (EDA) is Protection Coordination. This study is necessary to ensure proper protection discrimination and selectivity, preventing unnecessary or undesired tripping of upstream protective devices during electrical fault conditions.

Performing a protection coordination study for a new electrical system is relatively straightforward, especially with the aid of modern power system analysis software. However, conducting the same study on an existing or aging electrical system presents a greater challenge. Legacy protective devices and obsolete technologies within the power network can become critical elements that must be carefully evaluated and coordinated to ensure the safe, selective, and reliable operation of an industrial plant.

One major challenge is that the Time-Current Characteristic (TCC) curves of obsolete protective devices may no longer be available in the built-in libraries of modern power system software. The question then becomes: How can these legacy protective devices be incorporated into a protection coordination study to ensure proper discrimination, reliability, and safe plant operation, especially when they represent critical points in the electrical network?

This is where advanced engineering knowledge, supported by modern technology, becomes invaluable.

The figures below show the original hard-copy TCC curve of an obsolete protective device obtained from an old product catalogue and the corresponding extracted TCC data points converted into an Excel-compatible format. These data points can then be incorporated into the power system model, allowing the legacy protective device to be represented and evaluated alongside modern protection equipment.

With the combination of engineering expertise, historical technical data, and advanced digital tools, even obsolete protective devices can be incorporated into a modern power discrimination and protection coordination study.

Technology may evolve, but existing electrical systems must still operate safely and reliably. Through proper engineering analysis, we can bridge the gap between legacy protection technology and modern power system analysis to achieve a safer, more reliable, and better-coordinated electrical network.

Is Your Rooftop Solar System Losing Hundreds of Thousands of Pesos Every Year?

Many commercial and industrial rooftop solar PV systems installed beyond the Net Metering Program experience 20–40% of their annual solar generation being exported back to the utility grid. Instead of maximizing the value of every kilowatt-hour produced, a significant portion of the solar energy is exported back to the grid and counted as consumption, resulting in substantial lost savings.

For example, a rooftop solar PV system generating 150,000 kWh per year may experience reverse power flow equivalent to an annual opportunity loss of approximately ₱120,000 to ₱480,000, depending on the amount of exported energy and the applicable electricity tariff. This is often the result of oversized PV systems, poor system design, and the absence of an effective Zero Export Control strategy.

At 120 Vector Consultancy & Engineering Services, we specialize in designing high self-consumption rooftop solar PV systems that maximize your investment while minimizing reverse power flow. Our engineering approach is based on advanced power system analysis and optimization, ensuring that your solar energy is consumed where it delivers the greatest economic value.

Our expertise includes:
1. Optimum Rooftop PV Sizing
We perform detailed load profile analysis and power system studies to determine the ideal PV system capacity that maximizes energy production while minimizing unnecessary energy export.

2. Advanced Zero Export Control Solutions
We design and implement intelligent zero-export control systems that prevent unwanted reverse power flow to the utility grid, allowing more solar energy to be utilized on-site and improving your project's financial return.

3. Intelligent Energy Dispatch and Self-Consumption Optimization
Our rooftop solar systems are engineered using optimization principles like the Lagrangian Function concept employed in modern power systems. By intelligently coordinating the operation of the solar PV system, utility supply, and battery energy storage (when applicable), we maximize self-consumption, minimize electricity costs, reduce demand charges, and improve the overall return on investment.

Maximize every kilowatt-hour. Minimize energy waste. Increase your return on investment.

For expert design and implementation of high-performance rooftop solar PV systems, Zero Export Control, PV Curtailment Analysis, Distribution Impact Studies, and Self-Consumption Optimization, contact 120 Vector Consultancy & Engineering Services today.
