332 results about "Collocation method" patented technology

In mathematics, a collocation method is a method for the numerical solution of ordinary differential equations, partial differential equations and integral equations. The idea is to choose a finite-dimensional space of candidate solutions (usually polynomials up to a certain degree) and a number of points in the domain (called collocation points), and to select that solution which satisfies the given equation at the collocation points.

Low emission high-power staged-combustion gas burner and gas collocation method thereof

The invention belongs to the technical field of industrial gas burner and relates to a low emission high-power staged-combustion gas burner. The staged-combustion gas burner is characterized in that a swirling machine, a flame stabilizing plate, a central canister and a middle pipe are coaxially arranged in the throat of the burner main body from outer to inner, wherein the flame stabilizing plate is provided with a gas gun which is axially fixed and has same uniformly distributed radial lines. The gas collocation method comprises the following steps: (1) collocating no gas in a direct air channel, in which is low-speed central cooling air, (2) mixing the high-speed swirling air entered from a swirling air channel with the gas jetted from a small gas hole B on the gas gun along the radialdirection till reaching to the semi-premixed state before emerging from the throat of the gas burner, and (3) face-to-face jetting the gas from a big gas hole on the top of the gas gun, the high-speed swirling air and the high-speed peripheral axial air flow so as to form non-premixing diffusion combustion. Because of the air, the staged gas branch supply, the premixing combustion and the non-premixing diffusion combustion, the combustion is uniform and NOx is prevented from being generated. The discharge amount of NOx of the gas burner is 70% lower than that of the common burner in the priorart.

ActiveCN101431254ASolve problems that are difficult to expressData processing applicationsCircuit arrangementsVirtual terminalConnection number
The invention relates to a method for configurating a virtual terminal of an intelligent device GOOSE in a digitalized substation, comprising the following steps: at least respectively defining the opening-inserting logic 1-i of the intelligent device as virtual terminals IN1-INi, and defining the opening-outgoing logic 1-j as virtual terminals OUT1-OUTj; expressing configuration of each intelligent device GOOSE in the form of connection in accordance with the principles of relay protection based on the intelligent device; respectively defining the terminal logic connection 1-k as LL1-LLk; arranging and re-expressing the configuration of the intelligent devices GOOSE in form of a list according to the logic connection based on virtual terminal logic connection; a GOOSE figuration list consists of the virtual terminal logic connection and the corresponding starting point and end point, wherein, the logic connection consists of two lists of the logic connection number LLk and the logic connection name. In this invention, the method can express network-transmission-based GOOSE digital signals in the form of the virtual terminals, so that personnel in charge of designing, construction, debugging, operation and maintenance of the intelligent device can intuitively read the opening-inserting logic, the opening-outgoing logic, exit logic and the like; in addition, the method can successfully solve the problem of difficult expression of GOOSE protective configuration on the drawing board, thus realizing construction according to the drawing, greatly improving efficiency of construction and debugging, meeting the requirement that 'digitalized substation is constructed by designing'.
