    Abstract: A photovoltaic power generation system and a conversion circuit. Two groups of photovoltaic arrays are cascaded by using the conversion circuit disposed in the photovoltaic power generation system to effectively increase an input voltage of a DC/AC conversion circuit. In this way, a cable with an existing diameter specification can improve current transmission in the photovoltaic power generation system, to effectively reduce costs of the photovoltaic power generation system. A voltage to earth at an intermediate node in the conversion circuit is adjusted to a first preset value, so that both an absolute value of a voltage to earth of a first group of photovoltaic arrays and an absolute value of a voltage to earth of a second group of photovoltaic arrays are less than a first threshold.

  • Patent number: 11926587
    Abstract: Disclosed herein is a process for upgrading a raffinate butene (C4 Raffinate) stream to propylene which can produce polymer grade propylene (PGP) by a metathesis process, without consuming fresh ethylene as a feedstock. By recycling ethylene byproduct in the metathesis equilibrium, propylene selectivity can be further improved without negatively impacting butene conversion. Additionally, upon PGP separation, this technology can provide an effluent acceptable for alkylate production by achieving a balanced butene conversion and heavies coproduction. The disclosed process is a relatively low temperature process which can be deployed as a drop-in option for conventional ethylene/butene metathesis unit and provide additional flexibility to existing operations to balance the supply and demand of C2-C4 light olefins.
