This work presents a development kit to simulate the behavior of load flow an Voltage Stability of a power system. The network is designed and implemented to be useful as a tool in engineering studies and laboratory practices; also the measurement of steady state is compared with its digital behavior simulation using Power World software. The system configuration has been extracted from one similar typical network used in the literature of power systems. Basically it has an infinity bus, two generators, loads, six transmission lines that permit also synchronization tests and making digital and analog measurements. The generators, loads as a constant impedance (resistors, capacitors and reactors) and the infinity bus belong to a Lab-Volt commercial brand, transmission short line models are designed using easy acquisition materials. In addition the use of a digital instrument of AEMC series permits the capture of information.
