EDP's experience in optimising in-service protection system units

With a focus on providing a higher quality of service (QoS), while minimising Capital Expenditure (CAPEX) and Operating Expenses (OPEX), EDP Distribuição (EDPD) developed a programme to optimise its current protection asset base that spans along several generations and technologies, and, consequently, with different levels of protection functions. This programme consisted of an exhaustive revision of all medium-voltage (MV) protection function settings, comprising a total of 484 substations and switching stations, and over 5100 feeders within the entire mainland Portugal distribution grid. The main goals were to ensure protection relays coordination, guarantee sensitivity for electrically distant short-circuits and minimise voltage dips duration. Firstly, EDP's Protection and Automation Department used DPlan to conduct systematic short circuit and protection studies. To optimise this process, reducing man-hours needed, EDPD and AmberTREE worked together to develop improvements within the short-circuit and reporting modules. With the newly optimised protection settings, EDPD advanced toward in-field implementation, resulting in more than 6600 protection function changes, preventing 190 potential coordination failures and reducing the voltage dips duration in 1197 MV feeders. EDPD expects to improve significantly QoS and reduce customer complaints regarding voltage dips and short interruptions by using the existing asset base, while keeping the costs low.

Protection scheme for energy storage systems operating in island or grid-connected modes

In 2015 Energias de Portugal (EDP) Distribuição (EDPD) decided to install a Storage system in its distribution grid that would be prepared to operate connected to the grid offering flexibility and services to the grid but also in island mode with a Client which was EDPD's partner in this project. EDPD, Siemens and Instituto de Engenharia Sistemas e Computadores – Investigação e Desenvolvimento (INESC ID) focused on the analysis of the response the ESS to faults either connected to the network or isolated from it. To ensure the safe operation in both modes new protection schemes were studied and a solution that fulfils the requirements was proposed and adopted. To validate all calculations and simulations made during the research phase, EDPD performed several on site tests which included real short-circuit experiments. EDPD verified that some of the results obtained in these on site tests were different from the simulations and theoretical calculations. Based on the studies and real tests, EDPD protections and automation department developed a two group setting to be applied to the ESS, one group to be used when in parallel with the grid and another to be used when in island mode. This proposed scheme insures the safe operation of this new type of asset.

Adaptive Neural Network Algorithm for Power Control in Nuclear Power Plants

The aim of this paper is to design, test and evaluate a prototype of an adaptive neural network algorithm for the power controlling system of a nuclear power plant. The task of power control in nuclear reactors is one of the fundamental tasks in this field. Therefore, researches are constantly conducted to ameliorate the power reactor control process. Currently, in the Department of Automation in the National Research Nuclear University (NRNU) MEPhI, numerous studies are utilizing various methodologies of artificial intelligence (expert systems, neural networks, fuzzy systems and genetic algorithms) to enhance the performance, safety, efficiency and reliability of nuclear power plants. In particular, a study of an adaptive artificial intelligent power regulator in the control systems of nuclear power reactors is being undertaken to enhance performance and to minimize the output error of the Automatic Power Controller (APC) on the grounds of a multifunctional computer analyzer (simulator) of the Water-Water Energetic Reactor known as Vodo-Vodyanoi Energetichesky Reaktor (VVER) in Russian. In this paper, a block diagram of an adaptive reactor power controller was built on the basis of an intelligent control algorithm. When implementing intelligent neural network principles, it is possible to improve the quality and dynamic of any control system in accordance with the principles of adaptive control. It is common knowledge that an adaptive control system permits adjusting the controller’s parameters according to the transitions in the characteristics of the control object or external disturbances. In this project, it is demonstrated that the propitious options for an automatic power controller in nuclear power plants is a control system constructed on intelligent neural network algorithms.

A project-oriented approach for power electronics and motor drive courses

Power electronics and motor drives are major topics covered in undergraduate electrical engineering courses. Nevertheless, current teaching methods are usually based on intensive mathematical analysis, which can be difficult for students to understand but mainly to apply. This article provides ideas and practical experiences of a project-oriented approach implemented in power electronics and motor drives courses at the Automation and Control Department of the Universidad Autónoma de Querétaro, Querétaro, México. By using a microcontroller-based motor drive and a more practical approach in class, it is possible to introduce students to these courses in a more attractive and efficient way. The results presented prove that this methodology improves student competency, increases motivation and promotes teamwork in such technical courses.
