[0002] The traditional main power station on the offshore gas field platform uses a gas turbine generator set or a reciprocating dual-fuel generator set. When the load of the main power station on the offshore gas field platform is small, even lower than 2000-3000kW, the above two generator sets have investment and fuel costs. Defects such as high operating costs
For a gas turbine generator set, its thermal efficiency is low, that is, to generate electricity with the same power, the fuel consumed by a gas turbine generator set is far greater than that of a reciprocating dual-fuel generator set
In addition, limited by the specifications of the gas turbine generator set, the general ISO power is greater than 3500kW, so there is a long-term low-load operation condition of the gas turbine generator set, which makes the thermal efficiency of the gas turbine generator set lower, that is, the gas turbine generator set The energy efficiency of the flat generator set is low
For reciprocating dual-fuel generator sets, diesel ignition is required for their operation, so there are disadvantages such as high operating costs

Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. The present invention uses a diesel power generation system to connect several natural gas power generation systems in parallel. Since the connection and control methods of several natural gas power generation systems are the same, it will only be described in detail by taking a diesel power generation system in parallel with a natural gas power generation system as an example:
[0015] like figure 1 As shown, the present invention includes a natural gas power generation system and a diesel power generation system, wherein the natural gas power generation system includes a natural gas source 10, and the natural gas source 10 communicates with a reciprocating gas generator set 12 through a pipeline 11. A one-way valve 13 is provided. The reciprocating gas generating set 12 comprises a reciprocating gas generating set 120, a gas filter 121, a central coo...

The invention relates to a main power plant for an offshore gas field platform and an application method of the main power plant. The main power plant comprises a plurality of natural gas power generation systems connected in parallel and a diesel oil power generation system connected with the natural gas power generation systems in parallel. Each natural gas power generation system comprises a natural gas source and a gas power generator set communicated with the natural gas source through a first pipeline. The diesel oil power generation system comprises a diesel oil source, a diesel oil daily tank communicated with the diesel oil source through a second pipeline and a diesel power generator set communicated with the diesel oil daily tank through a third pipeline. The output end of the diesel oil power generator set is provided with a fourth pipeline for conveying the residual diesel oil in the diesel oil power generator set back to the diesel oil daily tank. The main power plant further comprises a control system for controlling the diesel oil power generation system and the natural gas power generation systems or the natural gas power generation systems to operate in a controlled mode.
