Electrical cogeneration system and method

摘要

An electrical cogeneration system and AC coupling method for efficiently distributing power from multiple AC sources. The system includes a main AC source, an AC generator, a solar panel, and an automatic transfer switch. The main AC source and the AC generator are connected to the transfer switch. The system also includes a DC/AC inverter, which is in communication with the solar panel. The transfer switch and the inverter are both connected to a common AC load panel where the power provided by the solar panel, the AC generator, and the main AC source is used to satisfy a common electrical load. The system further includes a system control device that is in communication with the inverter and the transfer switch and is capable of selectively determining power input to the AC load panel. An AC coupling method for distributing power from multiple AC sources is also provided.

1. A method of synchronously paralleling multiple AC power sources, the method comprising the steps of:
a) providing a paralleling system comprising a main AC power source, a synchronous AC generator, a solar panel, a solar controller, said solar panel linked to said solar controller, a DC disconnect, said solar controller connected to said DC disconnect, an AC disconnect, a transfer switch, a generator controller, a load controller, said generator and load controllers connected to said synchronous AC generator, said main AC power source and said load controller connected to said transfer switch, an inverter, said inverter in communication with said AC disconnect, a load panel, said transfer switch and said inverter connected to said load panel, a system control device, said system control device in communication with said inverter, said transfer switch, said solar controller, said generator controller, and said load controller; b) measuring an electrical load by said system control device at said load panel; c) selecting an AC power source to satisfy the electrical load; d) configuring the system control device to match AC power produced by the synchronous AC generator and the renewable power source to power produced by the main AC power source; e) detecting a reverse power flow event at the AC synchronous generator; and f) throttling power produced by the renewable power source to decrease available AC power until the reverse power flow event ceases.
