The application discloses an oscillation suppression method and system of a grid-following and grid-forming inverter hybrid system, and comprises the following steps: establishing a grid-following inverter decomposition model, and separating out a negative damping component causing instability of the grid-following inverter; designing a compensation term based on the negative damping component, injecting the compensation term into a grid-forming inverter, and reshaping output impedance of the grid-forming inverter to offset the influence of the negative damping component of the grid-following inverter on system stability. The negative damping component is injected into the grid-forming inverter after being taken in reverse, and a compensation term of the output impedance of the grid-forming inverter can be calculated, so that the influence of the negative damping component of the grid-following inverter on system stability is offset.

A split mixed refrigerant ("MR") natural gas liquefication system, where low-pressure ("LP") and medium pressure ("MP") MR compressors are driven by a first gas turbine and a propane compressor and a high-pressure ("HP") MR compressor is driven by a second gas turbine, is disclosed. The split MR liquefication system is configured to adjust the characteristics of the HP MR compressor to require less power when less power is available and more power when more power is available compared to the system's design point. Such adjustments allow for shifting the balance of power between the propane compressor and the HP MR compressor to improve LNG production efficiency.

A reciprocating compressor comprising one or more modules, each of which comprises a plurality of radial cylinders within which pistons slide, the connecting rods of which receive motion through the same bushing mounted on the crankshaft, wherein the rotational couplings are lubricated by means of special conduits that deliver lubricant directly to the sliding surfaces.
