1. Mbelata njikwa.

Iji hụ na nkwụsi ike nke arụ ọrụ yiri nke mmanụ dizel generator, a na-anabatakarị nchịkwa nchịkwa, ya bụ, P / f droop control na Q / V droop control na-eji nweta ugboro na voltaji kwụsiri ike.Usoro njikwa a na-emetụta mmepụta ike na-arụ ọrụ site na nkeji ọ bụla.Iche iche njikwa na reactive ike, na-enweghị mkpa nkwurịta okwu na nchikota n'etiti nkeji, iji nweta ọgbọ-na-ọgbọ akara n'etiti nkeji, na iji hụ na itule nke ọkọnọ na ina na ugboro kwụsie ike nke dizel generator set yiri usoro.

Njikwa droop na-anakwere voltaji na njikwa aka-loop dị ugbu a.Ntugharị dị n'ime dị ugbu a nwere ngwa ngwa nzaghachi ngwa ngwa, nke a na-eji eme ka ogo ike nke igwe na-emepụta ihe.Onye na-ahụ maka mgbanaka elu voltaji nwere ọsọ nzaghachi dị ike na-adị nwayọọ, nke nwere ike ijikwa voltaji mmepụta nke sistemụ ahụ wee mepụta ntụaka akaghị n'ime.Signal.Mbụ, jiri modul nha na-anakọta voltaji na ugbu a nke ibu ibu, gbakọọ ozugbo na-arụ ọrụ na reactive ike nke generator set, wee gafere ala-agafe nyo LPF iji nweta kwekọrọ ekwekọ nkezi nkezi;na-eche na ugboro ugboro gosiri na-agba ọsọ, generator set si mmepụta ike arụ ọrụ P, F, U bụ ugboro na gosiri voltaji njupụta nke ike usoro n'otu n'otu.A na-enweta ugboro ugboro mmepụta na iwu njupụta voltaji site na njikọ droop, mgbe ahụ, a na-emepụta voltaji ntụaka site na njikọ njikọ voltaji.Mgbe ahụ, voltaji ntụaka ga-eji dị ka voltaji na nke ugbu a abụọ njikọ njikwa.

2. Usoro nhazi ngwa ngwa (nchịkwa ike na-arụ ọrụ).
