What Our Students Say

Trusted by 11,000+ Power Engineers Worldwide | 4.9/5 Average Rating

Ezenwa Udoha

"I am so impressed with the instructor – I was having difficulty in my project involving Simulink for Power Systems, but when I attended the courses taught by Ricardo and also had a private conversation with him, his response was very fast and accurate. I can say the support I got from Ricardo was excellent. I give Ricardo FIVE STARS!"

Satoru Sotoyama

"It's well delivered and also quite engaging such that I was able to finish it in one sitting! This course is an excellent refresher for symmetrical components and fault analysis."

Geno Stewart

"The electric power course offerings by Romero Engineering Company are some of the best continuing education courses I've ever had. The courses were very comprehensive and easy to understand, and Mr. Romero provided me high quality instruction. The Simulink tutorials were especially helpful for my master's coursework. Highly recommended!"

Symmetrical Components

3 sections | 25 lectures | 2hr 47min

This course covers symmetrical components in a great amount of detail. Symmetrical components is a mathematical tool used for the analysis of unbalances in power systems, including faults. Because of this, a thorough understanding of symmetrical components is key for aspiring protection engineers.


Busbar Protection

2 sections | 9 lectures | 2hr 26min

This course covers low-impedance and high-impedance bus differential protection. These protective elements are found in modern microprocessor-based relays, such as the SEL-487B and SEL-587Z protective relays. This course is designed for practicing protection engineers.


Transformer Protection

3 sections | 12 lectures | 3hr 15min

This course covers transformer protection in detail. We will discuss the different transformer connections and the use of protective elements specific to transformer protection, such as phase differential (87P), ground differential (87G/REF), volts/hertz (24), as well as how to use both phase and neutral overcurrent elements (50P/51P/51N) for transformer protection.


Protective Relay Logic

3 sections | 13 lectures | 2hr 15min

This course covers how to implement different logic schemes using protective relays. Focusing on SEL protective relays, we will discuss what logic gates, timers, and latches are, and will see how to use these elements to develop logic schemes, such as breaker failure, permissive tripping, overcurrent blocking, and automatic reclosing schemes.


Power System Analysis

12 sections | 99 lectures | 14hr 45min

This course covers all concepts of power systems analysis. Power system analysis is the core of power engineering and its understanding is therefore essential for a career in this field. In this first course you will learn about three-phase power, generator, transformer, and transmission line models, how to analyze power systems using the per-unit system, how to perform load flow in power systems and how to analyze short circuits (faults).


MATLAB/Simulink for Power System Simulations

3 sections | 21 lectures | 4hr 40min

This course is designed to allow you to simulate power systems in MATLAB/Simulink. This course not only gives a review of the theory of how power systems operate, but also gives several examples on how to run different types of power system studies using MATLAB/Simulink.


AC Electric Circuit Analysis

3 sections | 25 lectures | 3hr 20min

This course covers the analysis of AC circuits, including important concepts, such as phasors, impedance, admittance, instantaneous power, RMS quantities, power factor, and complex power.


Power Electronics Fundamentals

10 sections | 24 lectures | 3hr 45min

This course is designed to provide a complete overview of one of the main areas of electrical engineering and power engineering: power electronics. The three main types of power electronics devices (i.e., rectifiers, dc-to-dc converters, and inverters) are discussed in detail in the lectures. For each device, the ideal circuit is discussed along with different circuit topologies to provide a wide range of practical uses.


MATLAB/Simulink for Power Electronics Simulations

5 sections | 33 lectures | 6hr 55min

This course is designed to allow you to simulate any power electronics device in MATLAB/Simulink, including rectifiers, dc-to-dc converters, and inverters. This course not only gives a review of the theory of how rectifiers, dc-to-dc converters, and inverters work, but also gives several examples on how to simulate these devices using MATLAB/Simulink. The MATLAB/Simulink models for the power electronics devices created during the lectures are available for download with each lecture.


Electric Circuit Analysis

10 sections | 66 lectures | 5hr 54min

This course is designed to provide a complete overview of electric circuit analysis used in electrical engineering, including simplification of complex circuits, advanced circuit analysis techniques, and analysis of circuits during transients.

Protection Fundamentals

This course covers fundamental topics in power system protection and control, such as what protective relays are, types of faults, instrument transformers (CTs and PTs), and the basics of protective elements, such as overcurrent (50/51), under/over voltage (27/59), under/over frequency (81), distance (21), and differential (87).


Transmission Line Protection

This course covers transmission line protection in detail. We will discuss transmission line construction and the use of protective elements specific to transmission line protection, such as ground overcurrent (50G/51G), phase and ground distance (21P/21G), and out-of-step/power swing (68). We will also discuss the different pilot schemes in detail, such as line current differential (87L), permissive overreaching transfer trip (POTT), and directional comparison blocking (DCB).
