Advance Key Features
8 of SCADA System Key Features
1. 2 SCADA Systems (1 SCADA for Mechanical Power Plant + 1 SCADA for Electrical Power System).
The APS12 Advanced Smart Grid Power System is unique in the world. With two different SCADAs, one for Mechanical Power Plants control (SCADA II) and
other for Electrical Power System control (SCADA I) allows user to work in an authentic operations control room. Each SCADA is installed in a control bench with
three touch screens and one panoramic screen. In total, the APS12 has eight screens to supervise, control and acquire all information about the mechanical
and electrical power systems.
Two SCADAs are engaged so that the actions carried out in the mechanical power plant elements are reflected in the electrical power system and vice versa.
This means that if the user increases the steam turbine flow in the mechanical power plant hence synchronous generator will increment the speed and, in
consequently, the grid frequency and any other electrical parameters will change. On the other hand, if the load consumption changes the steam turbine flow
will change too in order to compensate the increment or decrement torques.
These two SCADAs offer a great of possibilities because all actions, measurements, alarms, decisions, orders, configurations etc. are centralized in the control
panels.
2. 12 Mechanical Power Plants available. Any other available on request.
The APS12 offers the possibility to work up to 12 mechanical power plants. Optionally, other power plants are available on request.
The 12 Mechanical Power Plants allows user to understand how work the most important power plants of the world.
 PPE/CC. Combined Cycle Power Plant.
 PPE/NU. Nuclear Power Plant.
 PPE/FD. Diesel Fuel Power Plant.
 PPE/GA. Gas Power Plant.

3. All hardware and software fully designed by the wide EDIBON, more than 20 engineers team (Electrical, Mechanical, Telecommunications,
Software, etc.).
The APS12 is the result of work months of a great engineer's team: electronics, electrical, mechanicals, telecommunications and software engineers. These
were the formula to get this authentic power machine. This one represents truly multiple mechanical and electrical power systems with tens of possible
configurations: one gas turbine, one or two generators, one transmission line, two transmission lines, three transmission lines, etc. Besides, this modular option
allows couple smart grid elements focused in the final customer such as smart meters, home energy management systems, net-metering elements, etc.
4. All electrical and mechanical changes done as real industrial system by using six touch screens and two panoramic screens.
The APS12 control panels include up to eight screens, six of them are touch. But, What can do the user with all these screens?
In a power plant the most important thing is that the operator can visualize in all time the system control variables such as circuit breakers and disconnectors
state, nodes voltage, turbine frequencies, synchronous generators output voltages, generator regulation states, power flows, transmission lines, protection
relays state, short circuits, etc. all these actions and much more can be carried out in parallel for the multiple associated screens.
5. To analyze the response at the Electrical Power System, after any action at the Mechanical Power Plant.
One of the most important things of the APS12 is that both Mechanical and Electrical Power Systems are engaged. When any condition changes in the
mechanical side, the electrical side responds automatically. For example, if the user increases the steam turbine flow, the synchronous generator speed will
change. If the load consumption changes, the synchronous generator torque will changes and the steam turbine flow will change automatically to compensate
the torque resistance. All these is possible thanks to more than ten PID integrated in the Power System.
6. To analyze the response at the Mechanical Power System, after any action at the Electrical Power Plant.
When any condition changes in the electrical side, the mechanical side responds automatically. For example, if the user increases the steam turbine flow, the
synchronous generator speed will change. If the load consumption changes, the synchronous generator torque will changes and the steam turbine flow will
change automatically to compensate the torque resistance. All these is possible thanks to more than ten PID integrated in the Power System.
7. Real values voltages up to 800.000 V. Any other condition available on request.
The APS12 works with safe voltage from 0 up to 400 VAC: synchronous generators work from 0 up to 420 VAC, transmission and distribution lines work from 0
up to 400 VAC and loads consumption work at 400 VAC too. However, in order to represent the same conditions of real power systems, these values are
scalable through the SCADA up to 800.000 VAC. On this way, the user will face to the same parameters and situations of real power generation, transmission
and distribution line systems.
8. 6 touch screens and 2 panoramic screens for remote control as in real operations control room.
These touch screens allow users remote control operations of the mechanical and electrical power system. More than 480 control variables are manage from
eight screens with unifilar diagrams, synchronization control panels, standard symbols, real time measurements, real short circuit tests for protection relays
training, etc.

The “APS12” has two levels revolutionary protection systems.
In the level 1, students and teachers can configure and manage actual protection relays manufactured by SEL (Schweitzer Engineering Laboratories from USA).
SEL revolutionized the protection industry by building the first microprocessor-based protective relays. These relays integrated, economized, and simplified the
art of transmission line protection while introducing two powerful tools: fault locating and event reporting.
The APS12 incorporates the following protection relays: differential protection relay, overvoltage protection relay, inverse power protection relay, under voltage
protection relay, over frequency protection relay, under frequency protection relay, distance protection relay, directional protection relay, overcurrent protection
relay, etc. However, as the students can make configuration mistakes, the “APS12“ has a second system protection or backup protection (level 2) in order to
avoid damages in the system.
7. Study of National Grid stability (voltages, power flows, generation VS consumption, etc).
System frequency is a continuously changing variable that is determined and controlled by the second-by-second (real time) balance between system demand
and total generation. If demand is greater than generation, the frequency falls while if generation is greater than demand, the frequency rises.
The APS12 allows work with these conditions, increasing and decreasing the demanded load, the power flows and voltages change. Hence the grid stability is
affected and it is very important the system regulation.
8. Analysis for effects of load characteristics on power systems.
Load characteristics will be changing from time to time and may affect the system voltage stability to some extent. In order to investigate the effects of load
characteristics on the system voltage stability the APS12 has three scalable inductive, capacitive and resistive loads. Besides, it includes advanced automatic
frequency and voltage controllers to compensate the load characteristic changes.

the like will usually have backup power sources such as standby generators, which will automatically start up when electrical power is lost.
The APS12 has been designed to study all these circumstances. Besides it includes a real diesel-generator group for energy recovery. When the user provokes a
short circuit and synchronous generators shut down, diesel generator starts automatically up to system stabilization is recovered.
2. Study of restoring the Mechanical + Electrical Power System, after a black out.
Once a black out appears, it is very important to know the most important steps to recover the normal operation of the mechanical and electrical power system.
The APS12 allows users to study these actions, how voltage and frequency controllers work after a black out, how protection relays are restored for a normal
operation, etc.

7. Distribution systems with automatic voltage regulator to study drop voltages compensation.
The APS12 consists of a distribution transformer voltage regulator. When generated energy is transported, an amount of losses appear as consequence of
Joule effect and others phenomena such as Ferranti effect. These losses produce a drop voltage in the end of the lines. This drop voltage has to be
compensated with the distribution transformer voltage regulator. Voltage regulator commutates the distribution transformer coils changing the relationship of
this one.

the system is ready to inject the fault. Once the fault is produced, according to the protection relays setting, the first level protections should act, if not the second
level protection (back-up protection) always act.
Fault conditions can occur in different situations and scenarios: in the synchronous generator, in the primary winding step-up power transformer, in any point of
transmission lines, in the distribution transformer. Besides, it is possible to set the short circuit type such as single phase short circuits, two phase short circuit,
three-phase short circuits with and without impedance.
