1. An electrical emulator system comprising:
an emulator assembly comprising:
a first plurality of first emulator circuit boards, each first emulator circuit board comprising:
a first controllable AC voltage source mounted to the first emulator circuit board, the first controllable AC voltage source having first input terminals and first AC output terminals;
a set of first input terminals electrically connected to first input terminals of the first controllable AC voltage source;
a set of first output terminals electrically connected to the first AC output terminals of the first controllable AC voltage source; and
a first processor electrically connected to the first controllable AC voltage source and configured to control the first controllable AC voltage source so as to provide AC voltage at the first AC output terminals for emulation of a first set of components of a modeled electrical power grid;
a first docking station having a set of first docking terminals for emulated line power, the first docking station comprising guides to removably receive each first emulator circuit board separately therein and align and electrically connect the set of first input terminals and the set of first output terminals to selected first docking terminals of the set of first docking terminals;
a second plurality of second emulator circuit boards, each second emulator circuit board of the second plurality comprising:
a second controllable AC voltage source mounted to the source emulator circuit board, the second controllable AC voltage source having second input terminals and second AC output terminals;
a set of second input terminals electrically connected to second input terminals of the second controllable AC voltage source;
a set of second output terminals electrically connected to the second AC output terminals of the second controllable AC voltage source;
a second processor electrically connected to the second controllable AC voltage source and configured to control the second controllable AC voltage source so as to provide AC voltage at the second AC output terminals for emulation of a second set of components of the modeled electrical power grid;
a second docking station having a set of second docking terminals for emulated line power, the second docking station comprising guides to removably receive each second emulator circuit board of the second plurality separately therein and align and electrically connect the set of second input terminals and the set of second output terminals to selected second docking terminals of the set of second docking terminals;
a first set of connectors electrically interconnecting selected first docking terminals of the first docking station so as to simulate a first bus of the modeled electrical power grid;
a second set of connectors electrically interconnecting selected second docking terminals of the second docking station so as to simulate a second bus of the modeled electrical power grid; and
a third set of connectors to electrically interconnect the first and second docking stations to simulate electrical connection of the first and second buses of the modeled electrical power grid.
