Adaptation of a Cogenerator with Induction Generator to an On/Off-Grid Operation Using a Power Electronic System

Cogeneration sources play a very important role in the power industry with dispersed renewable forced generation (e.g., photovoltaics and wind generators). They also fit into circular economy by increasing efficiency of fuel use, including biogas from agricultural or livestock waste. The aim our research was to develop an effective source electricity powered biogas. most features such are: operation on-grid off-grid mode, as well low cost device uncomplicated operation. In addition, Europe, connected grid must meet technical requirements “Network Codes Requirements for Generators” (NC RfG) network code. appropriate certificate is easier obtain using converter system source. For this purpose, induction generator small battery planned. A developed built, then tests were carried out various operating modes. During measurements, it confirmed that quality modes met. assumed maximum time voltage recovery after changing amounting 40 ms, not exceeded. Furthermore, limit values phase voltages unsymmetrical load, ±10% rated voltage, usage step change load longer than 2 s.
