Abstract: The disclosure provides a frequency support method, device and wind farm for a wind farm and belongs to the technical field of new energy power generation and grid connection. In the frequency support method, a state that can reflect a frequency modulation capability of a wind turbine is designed, measured, and recorded as a consistency factor of frequency modulation. Each wind turbine is controlled to exchange the consistency factors with two adjacent wind turbines. Each wind turbine combines its own consistency factors with the consistency factors of two adjacent wind turbines to generate consistent added power through a PI link and adjusts real-time frequency modulation output based on the consistency added power. In this way, the states of the wind turbines in the wind farm are similar during the frequency support process, so that a reasonable distribution of frequency support power is achieved.

Abstract: A method of retrofitting a building exterior with an insulation and cladding construction has a multitude of steps. One step involves placing rigid panel insulation members to certain areas of the building exterior. A subsequent step involves spraying polyurethane insulation foam to certain areas of the building exterior. And yet another step involves spraying cladding over the rigid panel insulation members placed at the building exterior, and involves spraying the cladding over the previously-sprayed polyurethane insulation foam. The sprayed cladding cures in-place and, once cured, constitutes a continuous and monolithic cladding exterior construction over the placed rigid panel insulation members and over the sprayed polyurethane insulation foam.

The oral Pt(IV) anticancer prodrug is synthesized by using oxaliplatin as a starting material, performing axial oxidation with H2O2 and neutralizing the oxidized product with 3-bromopyruvic acid.

Abstract: The solution can provide a switch-configurable diplexer architecture for dual-band communication. A first diplexer can have a first band for an interlink connection between an access point and a device and a second band for an intralink connection between the device and a second device. The first band and the pass band can be separated by a first gap. A second diplexer can have a third band for the first interlink and a fourth band for the intralink. The third band and the fourth band can be separated by a second gap. The first band and the third band, as well as the second band and the fourth band, can partially overlap. A processor can identify that the access point has selected, for the interlink connection, a first channel corresponding to the second gap and determine, responsive to the identification, to use the second diplexer for the intralink connection.
