Problems solved by technology

And if the rotating speed is further reduced, then for the existing various generators or known various voltage stabilization technologies, it is no longer possible to provide the power system with a voltage that guarantees normal operation.
Because of such a wide range of voltage changes, it has far exceeded the scope of application of various existing voltage regulation technologies.

Embodiment 1

[0014] Embodiment 1: Divide the coil elements in the stator windings of each phase in the generator into four parts that are physically and electrically identical in structure, and each part leads to a set of independent terminals. An array of electronically controlled switches is connected between the terminals of each adjacent two parts. Through the different on and off changes of the switches in the switch array, different series and parallel connections can be realized between the coil elements of the four parts, and the same name can be achieved. The direction of the current at the terminals remains the same.

[0015] When the generator is running at full speed, the four parts of the coil elements in the stator winding of each phase are connected in parallel, and the output is full voltage at this time. When the speed is reduced by half, the four parts of the coil elements are controlled by the on-off change of the electronically controlled switch array, and are connected...

Embodiment 2

[0019] Example 2: Divide each coil element in a generator stator winding into six discrete sub-element sections. The sub-elements in each element are located in the same stator slot, have the same electrical structure and independent terminal sets. An electric control switch array is connected between the connection terminals of every two adjacent sub-elements. The electronically controlled switch array is five switches controlled by a computer program, and each switch is respectively located between two nodes on the "I" connecting line and between each node and the line end. Such as figure 2 Shown, Y 1 -Y 6 It is six discrete sub-elements in one coil element, occupies the same stator slot, has an independent terminal group, and has the same electrical structure. In child element Y 1 with Y 2 There are five switches 1-5 controlled by computer programs indirectly, forming an array of electronically controlled switches. Similarly, switches 6-10 are subcomponents Y 2 wit...

Abstract

This invention discloses a separated across-the-line generation technology suitable for large scale rotation variance aiming at solving the problem of narrow effective zone of the present generator output voltage and low voltage usability by separating the coil elements of a stator winding or sub-elements of the coil element into even parts in the same structures, each leading out independent connector groups, and between two adjacent parts, switch arrays of realizing their serial or parallel connection and same current direction of the same kind ends are designed. A generator output voltage corresponds a very large rotation effective zone in certain fluctuation sphere to increase the voltage usability.

Description

[0001] Field [0002] The invention relates to a generator manufacturing technology, in particular to a split-point full-voltage power generation technology that adapts to a wide range of rotation speed changes. technical background [0003] The stator winding of the generator manufactured by the existing technology is composed of a plurality of coil elements made of insulated wires wound in the stator core, and each coil element (hereinafter referred to as "element") is generally composed of a single strand Insulated wires are made by winding several turns in the same stator slot, and of course there are components made by multi-strand wire parallel winding technology. In existing generators, the components are connected according to the requirements of different generators or a certain fixed rule to generate a group of terminals. Under ideal conditions, if the load is constant, the output voltage measured at the terminal is linear to the rotor speed of the generator. That ...
