Advanced Mechanical, Electrical and Smart Grid Power Systems (Utilities), "APS12", designed by EDIBON, are recognized as one of the most advanced and comprehensive systems on the market. Unlike other simulators, the Advanced Mechanical, Electrical and Smart Grid Power Systems (Utilities), "APS12", are real systems that allow the visualization and analysis of any electrical phenomenon present in real power grids, including short circuits, overcurrents, overvoltages, overfrequencies, reverse power, out-of-control generators, and blackouts.

Power System Components:

Generation System: Power generation is fundamental as it marks the beginning of all energy systems. From this point, transmission lines extend to distribution networks, supplying electricity to end consumers.

The efficiency and safety of this process depend on a wide range of control variables. What really sets the Advanced Mechanical, Electrical and Smart Grid Power Systems (Utilities), "APS12", apart from others is its ability to monitor more than 217 critical variables present in real power plants to ensure efficiency and safety in the operation of the turbine-generator unit. These variables range from manual turbine start/stop control to automatic generator synchronization. Additionally, it incorporates various protection relays that allow testing a wide variety of electrical faults.

The APS12 generation system allows a comprehensive and detailed approach to the investigation and replication of different real-life scenarios. Below are the key aspects of the study and analysis:

• Study and analysis of general control variables of the turbine-generator unit, providing a deep and detailed understanding of its behavior under various operating conditions.
• Remote control via the advanced EDIBON-SCADA software of the turbine-generator unit:

• Manual remote control of the turbine-generator unit:
  • Control of turbine frequency and generator voltage in island mode.
  • Control of active and reactive power of the generator in parallel-load sharing grid mode.
• Automatic remote control of the turbine-generator unit:
  • Operation, testing, and trials in island mode.
  • Operation, testing, and trials in parallel-load sharing grid mode.

• Study of control variables for different protection systems: Study of protection relays for the turbine-generator unit under various conditions of overcurrent, directional, overvoltage, etc.

Transmission/Distribution System: The Advanced Mechanical, Electrical and Smart Grid Power Systems (Utilities), "APS12", allow the monitoring of more than 111 key variables to ensure quality and safety in the transmission and distribution of energy. This system provides the operator with critical information on factors such as the length of power lines, energy losses, the impact of reactive power on the grids, overvoltages, and harmonic effects on the grid. Thanks to the integrated SCADA technology, it is possible to optimize system interaction and improve the overall efficiency of the power grid.

Main control variables:

• Opening/Closing of Disconnectors and Circuit Breakers: Precise control over the operations of disconnectors and circuit breakers in multiple transmission lines, ensuring safe and reliable distribution.
• Capacitive and Inductive Effects on Lines: Configuration and control of capacitive and inductive effects on transmission lines, essential for maintaining stability and energy quality.
• Distance Protection: Variables that configure distance protection, including transformers, impedances, and overcurrent elements in various zones and levels.
• Overcurrent and Negative Sequence: Detailed control of overcurrent and negative sequence, including adjustments for defined and inverse time for optimal grid protection.

The Advanced Mechanical, Electrical and Smart Grid Power Systems (Utilities), "APS12", incorporate advanced distance, overcurrent, and directional protection relays, which can be controlled and programmed through multiple variables.

Load System: The Advanced Mechanical, Electrical and Smart Grid Power Systems (Utilities), "APS12", monitor 158 critical variables, allowing full interaction with the load system and ensuring its optimal operation. Some of these variables are involved in processes such as reactive power compensation and the management of feeder protection relays, as well as the control and regulation of the load tap changer incorporated into the distribution transformer.
