Specific embodiments of the present application are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely exemplary of the application, which can be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as to not unnecessarily obscure the present application with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present application in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.
In the prior art, for example, after a nuclear power diesel generator is successfully connected to a grid, the actual rotating speed of the generator is pulled by a power grid, that is, the actual rotating speed is the same as the rotating speed of the power grid, or corresponds to the rotating speed according to a certain corresponding relationship. As for the generator, what is called a preset rotation speed that needs to be adjusted is different from the rotation speed of the power grid, that is, the rotation speed of the power grid is actually different, and under different loads, the relationship between the preset rotation speed and the rotation speed of the power grid also changes, how is the speed of the generator adjusted after grid connection? The application provides a specific speed regulation method.
Fig. 1 is a schematic flow chart of a speed control method of a generator according to an embodiment of the present invention, and fig. 2 is a schematic quantity relationship diagram of speed reduction curves according to another embodiment of the present invention. As shown in fig. 1 and 2, in one embodiment, the present application provides a method of regulating speed of a generator, the method comprising:
s101, receiving a preset trigger signal.
In this step, a specific step of triggering the subsequent processing by the trigger signal is provided.
And S102, responding to the trigger signal, regulating the speed of the generator according to a preset speed reduction curve to obtain a corresponding preset rotating speed under the target load of the generator, and realizing that the actual rotating speed of the generator corresponds to the rotating speed of the power grid according to a preset corresponding mode, wherein the speed reduction curve is a relation curve between the preset rotating speed and the actual rotating speed as well as the target load.
In this step, a specific step of responding to the trigger signal and regulating the speed of the generator is provided. The target load is a load which the generator needs to bear, and the rotating speed of the power grid is the rotating speed of the power grid and is the actual rotating speed of the generator after final speed regulation.
In this embodiment, a specific implementation of performing speed regulation after being triggered by the trigger signal is provided. In this embodiment, the speed-down curve may be used for speed adjustment, and first, a predetermined trigger signal is received. Then, regulating the speed of the generator according to a preset speed reduction curve to obtain a corresponding preset rotating speed under the target load of the generator, and realizing that the actual rotating speed of the generator corresponds to the rotating speed of the power grid according to a preset corresponding mode, wherein the speed reduction curve is a relation curve between the preset rotating speed and the actual rotating speed as well as the target load.
The speed drop curve relates to three physical quantities, namely the preset rotating speed, the actual rotating speed and the target load, after the preset rotating speed is set, the speed of the generator starts to suddenly drop because the generator is in the power grid until the final rotating speed of the generator corresponds to the power grid rotating speed in the power grid, in power control, the final rotating speed of the generator needs to be consistent with the power grid rotating speed, at the moment, the final rotating speed of the generator is the actual rotating speed which is finally output, and after different preset rotating speeds are finally balanced, different target loads need to be loaded if the actual rotating speed is consistent with the power grid rotating speed. In practical applications, for example, when it is expected that the generator will eventually be charged with the corresponding target load and the actual rotation speed is the grid rotation speed, the corresponding predetermined rotation speed is adjusted, and the predetermined rotation speed is adjusted by the speed-up-down button based on the switching value, i.e. the trigger signal, so that the target load is a result and is the expected load result, and the final actual rotation speed is the grid rotation speed.
When the preset rotating speed of the generator is adjusted, the preset rotating speed is rapidly reduced due to the fact that the preset rotating speed is incorporated into the power grid until the preset rotating speed is correspondingly consistent with the rotating speed of the power grid, the load borne by the generator is the target load, and the end point of the balance state is the state which needs to be achieved after speed regulation. Therefore, different predetermined rotational speeds can carry different loads when the actual rotational speed finally reaches a fixed value, i.e., the grid rotational speed. As shown in fig. 2, for points SP1 and SP2, the load is lifted by the speed-up signal of the switching value, and the speed-up signal is cancelled by the speed-down curve during the speed-up process, corresponding to the increase of the load. It can be seen that points a and B are balance points, at this time, the actual rotational speeds of the two curves are both consistent with the rotational speed of the power grid, and the abscissa reflects that the load of the first curve is small, and the load of the second curve is large, if we determine the load to be borne by the generator, the corresponding preset rotational speeds can be adjusted, and finally, the actual rotational speeds are balanced on the rotational speed of the power grid.
In an embodiment, the obtaining of the preset rotation speed corresponding to the target load of the generator by regulating the speed of the generator according to the predetermined speed reduction curve includes:
the method comprises the steps of configuring different output currents to correspond to different accelerator opening degrees, and adjusting the accelerator opening degree of a generator according to the different output currents so as to correspond to different loads, wherein the generator is a diesel generator.
In this embodiment, a specific control method how to adjust the opening degree of the accelerator is provided, and how is the preset rotation speed required in the speed regulation method? In this embodiment, the output current is adjusted by the output current, and when the output current is configured to correspond to the accelerator opening of the generator, different accelerator openings obviously correspond to different predetermined rotation speeds, because the predetermined rotation speed is an attribute of the generator itself, and thus, different accelerator openings can be adjusted to correspond to different predetermined rotation speeds.
In one embodiment, the actuator is used to adjust the magnitude of the output current.
In this embodiment, a specific implementation of the control of the output current by the actuator is provided.
In one embodiment, the actuator is a Haitezmann 2231 actuator or a Woodward actuator or an electric actuator.
In this embodiment, three specific types of the actuator are provided, the magnitude of the output current of the actuator can be controlled by adopting an upper computer, and the upper computer is provided with an operation interface and used for human-computer interaction. The output current of the hydantz-man 2231 actuator is 1000mA to 0 mA. The output current of the Woodward actuator is 200mA to 0mA, and the electric actuator is 4-20 mA. And after configuration is finished, the corresponding output current is defaulted to be in a grid-connected state, and the regulation of following electric wave fluctuation can be carried out. The previous embodiment was directed to large-scale regulation, and the regulation of the electric wave fluctuation of the current output is a follow-up fine adjustment.
Fig. 3 is a relation diagram of the number of speed reduction curves of synchronous grid connection of first speed reduction and then closing in another embodiment of the present invention, and fig. 4 is a relation diagram of the number of speed reduction curves of synchronous grid connection of first closing and then closing in another embodiment of the present invention. In an embodiment, before the step of obtaining the corresponding preset rotation speed of the generator under the target load by regulating the speed of the generator according to the predetermined speed reduction curve, the method further includes:
and configuring a pre-loading current value and/or a speed reduction rate and/or a pre-full-load throttle value for the speed reduction curve.
In this step, a specific embodiment of configuring the speed reduction curve with preload, speed reduction rate, and 110% load throttle is provided. Firstly, the trigger signal can be understood as a closing signal of the power grid, after the closing signal is triggered, an accelerator value is added to a current accelerator opening value, namely an unloaded accelerator, the upper computer can configure the pre-loading current value, and the speed reduction rate is the rotating speed correspondingly reduced from the unloaded accelerator to the fully loaded accelerator. The pre-full load throttle value may be defined as the output current corresponding to the generator with a 110% load throttle, and also as the maximum current of the generator under grid connection.
Based on the two grid connection processes, namely, a speed reduction signal is input firstly, and synchronous grid connection is carried out during closing; or firstly inputting a closing signal, wherein the generator is in a loaded state, and then the generator is subjected to speed reduction and synchronization grid connection. Therefore, in any mode, the switching value signal corresponds to a switching-on switching signal sent by the synchronizer, and the switching value signal corresponds to two switching value signals of switching-on and switching-off, namely the trigger signal.
As shown in fig. 3, for the first case, the abscissa represents the load percentage of the generator corresponding to the number of racks fully closed to fully opened, that is, how much load is configured for the generator, that is, the target load, and the ordinate represents the predetermined rotation speed to be controlled, for example, the output current is configured to be 0 to 1000mA, reverse control is performed, the actuator matching the heinzmann 2231 is used, the output current corresponding to point C in fig. 3 is configured to be 110% load throttle, the rate of speed reduction is 5%, the value of the pre-load current is 5%, and the no-load throttle position of the generator is the throttle value corresponding to point a.
When the generator is started just, the generator is in an idle state similar to a vehicle at the moment, that is, the output current corresponds to an idle throttle value at the moment, and when the trigger signal is received, that is, a speed reduction signal and a closing signal, the current throttle opening is identified, and the magnitude of the output current corresponding to the current throttle opening can be understood as the idle throttle value, and after the grid connection is successful, according to the pre-loading current value (the current value of 110% load throttle/1.1 — idle throttle current value) × 5%, the set rotating speed is actually increased in advance, and a new balance point of the rotating speed of the power grid is a point B. This is required to configure the preload current value after the trigger signal, which can effectively cancel out and prevent reverse power from occurring. The speed reduction rate can be referred to in the figure, the speed reduction rate corresponding to a point a (closing instant no-load throttle value) to a point C (setting 110% load throttle value) is 5%, and an AD straight line generated by connecting the point a and the point D can be used as the speed reduction curve, wherein a (current throttle current value, n1), D (110% load throttle current value, n2), wherein n1 is 1000rpm, n2 is 1000+1000 × 5% ═ 950rpm, and the current value of the 110% load throttle is configured by the upper computer as the maximum current limit value; and simultaneously generating a curve from the point A to the point E, namely A (the current accelerator current value, n1) and E (1000mA, 1000+1000 × 5 ═ 1050rpm), thereby obtaining a full-scale speed drop curve.
For the second situation, the grid connection adopts the synchronous grid connection of firstly inputting a closing signal and then cutting speed reduction in an isolated island.
As shown in fig. 4, after the generator is successfully started, the output throttle value is the throttle value corresponding to the point a, and when the closing signal is received, the generator is loaded with the target load in the no-load state, and then the target load runs from the point a to the point B; and receiving the speed reduction signal in the state, meeting a grid-connected condition, enabling both switching values to have signals, entering a grid-connected mode, taking a current value corresponding to the load at the moment of inputting the speed reduction signal as an unloaded accelerator, calculating curves corresponding to E, B, D points, wherein E (1000mA, 1000+ 5% rpm), B (current accelerator current value, 1000rpm) and D (110% load accelerator current value, 1000+ 1000% 5% rpm), obtaining two curves EB and BD from 3 points, and limiting the current value to a value corresponding to the 110% load accelerator current value.
Fig. 5 is a schematic diagram of a generator speed control system according to another embodiment of the present invention.

the grid 2 can be grid-connected by the generator 1;
the speed regulation controller 3 is used for regulating the speed of the generator 1 according to a preset speed reduction curve to obtain a corresponding preset rotating speed of the generator 1 under a target load after a preset trigger signal is sent, so that the actual rotating speed of the generator 1 corresponds to the power grid rotating speed of the power grid 2 in a preset corresponding mode, wherein the speed reduction curve is a relation curve between the preset rotating speed and the actual rotating speed as well as the target load.
And (4) carrying out logic processing on the switch misoperation in the grid-connected state.
And when the universal speed regulation controller meets the speed reduction state and the switch-on state, the universal speed regulation controller enters a normal grid-connected state and controls the diesel generating set to carry out normal load lifting. At the moment, if switching-on and switching-off occur, the controller can pull the accelerator rack to the corresponding position according to the no-load accelerator value set by the upper computer, and the diesel generator set is shown to be disconnected from the power grid. If the speed drop islanding occurs, the speed regulation controller collects the current rotating speed as a set rotating speed and keeps the accelerator rack stable; and if the rotating speed is reduced in the isolated island, entering logic (B, firstly inputting a closing signal, and then synchronously connecting the isolated island with the cutting speed reduction grid).
