In a renewable energy grid you can find many different nodes like wind turbines, PV-farms, eCar loading stations, storage devices, private and public house and business enterprises. EGSTON provides integrated turn-key test solutions and emulation systems to cover the whole range from science to R&D and certifications.

Multi-Use Test Benches for R&D

EGSTON offers you var­i­ous test bench­es for R&D labs, indus­try and research that pro­vide the whole bun­dle of stan­dard test devices like AC and DC sources, elec­tron­ic loads, AC and DC grid emu­la­tors, PV pan­el emu­la­tors, bat­tery emu­la­tors and even more.

What makes them unique is that they are mul­ti-use test bench­es. That means one and the same test bench can act as an AC-grid emu­la­tor, an elec­tron­ic load or as a PV pan­el emu­la­tor at dif­fer­ent times. And it is always the same hard­ware, just the con­fig­u­ra­tion and appli­ca­tion has been adapt­ed.

Everything you need for your tests just when you need it

We also design inte­grat­ed solu­tions that you can use e.g. for a PV invert­er test bench that acts as a grid emu­la­tor and a PV-pan­el emu­la­tor at the same time and where every part can act inde­pen­dent form the oth­er or inte­grat­ed to per­form com­bined test sce­nar­ios.

This mul­ti-use test bench approach reduces the num­ber of test devices that you need in your lab dras­ti­cal­ly. At the same time widens the flex­i­bil­i­ty to have exact­ly the test bench type you need by just select­ing the appli­ca­tion you want.

Up-to-date Certification

We have appli­ca­tions to run whole cer­ti­fi­ca­tion tests ful­ly auto­mat­ed. You just con­nect the device under test — and all tests with this spe­cif­ic set­up will be processed step by step auto­mat­i­cal­ly. And when new stan­dards are pub­lished you do not need to have a com­plete new test appli­ca­tion — you sim­ply param­e­trize and store the new test pro­ce­dure.

The freedom to create your own tests and emulation

P‑HIL is an extreme­ly pow­er­ful tool to design and per­form any test or emu­la­tion you want based on math­e­mat­i­cal mod­els like Mat­lab, Simulink or oth­er tech­nolo­gies. You just cre­ate your indi­vid­ual mod­el of a test set­up or a real world device and then upload it into the HIL real-time proces­sor and exe­cute it. Out of your mod­el the con­nect­ed pow­er ampli­fiers cre­ate volt­ages and cur­rents with­in a pow­er range of 50 kVA up to MVA.

Realistic test scenarios made easy

In this way you get a real life rep­re­sen­ta­tion of your indi­vid­ual sim­u­la­tion with­out being restrict­ed to lim­it­ed appli­ca­tions like stan­dard elec­tron­ic load emu­la­tors or AC Source gen­er­a­tors. And you are able to devel­op and emu­late your indi­vid­ual sce­nario like an emu­la­tion of house with dif­fer­ent pow­er con­sumers and ener­gy sources like a small PV sys­tem includ­ing the change of ener­gy con­sump­tion and gen­er­a­tion over a whole day, a month or dur­ing sum­mer and win­ter­time.
