Specifically, in the prior art, for the self-powered devices of the wind turbine generator, a unified control manner is usually adopted, that is, each self-powered device works simultaneously or is in a standby state simultaneously, but the long-time continuous work and standby can increase the power consumption of the self-powered devices and reduce the service life of the self-powered devices. Therefore, the scheme proposes: firstly, self-powered equipment is classified according to the functions of the self-powered equipment and mainly divided into first type self-powered equipment and second type self-powered equipment, wherein the first type self-powered equipment is influenced by the operating state of a wind turbine generator set and environmental factors in the working process, and the second type self-powered equipment is basically only influenced by the environment in the working process, so that different control logics are adopted for matching different operating limits for the self-powered equipment on the basis of different parameters aiming at the first type self-powered equipment and the second type self-powered equipment, the respective self-powered equipment is controlled to operate on the basis of the operating limits corresponding to the respective self-powered equipment, the unified fine management and intelligent adjustment of the self-powered equipment are realized, the problem of high self-power consumption of the wind turbine generator set can be effectively solved, the service life of the self-powered equipment is prolonged, and the fault rate of the self-powered equipment is reduced, the utilization hours of the wind generating set are increased, and the economic operation level of the wind generating set is improved.
Further, the self-powered device at least comprises: a temperature adjusting device, a humidity adjusting device and an illuminating device;
the first type of self-powered device comprises: a temperature adjusting device;
the second type of self-powered device comprises: a humidity control apparatus and an illumination apparatus.
Specifically, the temperature adjusting device is a device for adjusting the ambient temperature of the wind turbine generator, so as to radiate heat generated by the wind turbine generator to the outside, so as to ensure that the wind turbine generator is located in a normal working temperature interval, the temperature adjusting device may include an air conditioner, a fan, a water cooling device and the like, and the setting position and the installation mode of the temperature adjusting device are common knowledge of those skilled in the art, and are not repeated here. Humidifying equipment is the equipment of adjusting wind turbine generator system place environment humidity, guarantees that wind turbine generator system is in normal operating humidity interval, avoids because humidity too big leads to short circuit, unit corruption etc to increase the life of unit, humidifying equipment can include dehumidifier, dehumidifier etc. and its position of setting, mounting means are the common general knowledge of technical person in the field, and here is no longer repeated. The lighting device is used for increasing the brightness in the wind turbine generator, such as the brightness in the tower bottom, the tower, the engine room and each electrical cabinet, and the setting position and the installation mode of the lighting device are common knowledge of those skilled in the art, and are not described herein again.
In another embodiment, the self-powered device further comprises: fire-protection equipment and monitoring equipment. The fire-proof equipment is used for spraying fire extinguishing agent when a fire disaster occurs so as to prevent the fire from spreading, and comprises a controller, an action mechanism, a fire extinguisher and the like, wherein when the controller receives an instruction, the action mechanism acts to enable the fire extinguisher to spray the fire extinguishing agent, the setting position and the installation mode are common knowledge of people skilled in the art, and the details are not repeated. The monitoring device is used for collecting sound and video signals in the wind turbine generator, and comprises a sound sensor, a camera and the like, and the setting position and the installation mode of the monitoring device are common knowledge of technicians in the field, and are not described herein again.
Further, the operation state of the wind turbine generator comprises: shutdown state, standby state, startup state, grid-connected state, shutdown process, and maintenance state.
Specifically, the shutdown state is a state that the wind turbine generator is in fault-free slow-speed operation and has no power output, the impeller freely idles at the feathering position of the blades, the rotating speed of the generator is lower than 2rpm, and the rotating speed of the generator is lower than 3rpm under the condition of strong wind. The standby state is a process from the shutdown state to the operation of the wind turbine generator, when a main control system of the wind turbine generator receives a starting instruction or meets a self-starting condition, the main control system sends a starting instruction to a converter of the wind turbine generator, the converter carries out pre-charging after receiving the starting instruction, pre-charging voltage rises to a preset value and then attracts a network side breaker and a machine side breaker, the converter sends a signal to be operated to the main control system after the breaker is switched on, the main control system controls blades to change the blades from the shutdown position to the standby position after receiving the signal with operation, and the blade positions are at the position of 89 degrees again when the main control system is in the standby state. In the starting state, the rotation speed of the impeller of the wind turbine generator is continuously set for a set time and then the generator is subjected to a rotation speed increasing stage, specifically, before the rotation speed reaches 8.8rpm, the variable pitch speed is 1 degree/second, and after the rotation speed reaches 8.8rpm, the variable pitch speed is 1.5 degrees/second. The grid-connected state is that after the rotating speed of an impeller of the wind turbine generator reaches a set grid-connected rotating speed, the wind turbine generator enters a grid-connected stage, a main control system receives a grid-connected signal and sends a required torque value or current value to a converter, the converter executes the required torque value or current value, and the wind turbine generator enters a power generation state. The shutdown process is that when the main control system receives a manual shutdown instruction, a fault occurs, and environmental faults such as strong wind, small wind and the like, the slope of the main control required torque is reduced, the blades feather at a set speed, the operation instruction of the converter is stopped after the rotating speed of the impeller is less than the set rotating speed, the converter stops modulation, and the unit enters a shutdown state after the rotating speed of the impeller is less than the set shutdown rotating speed. In a shutdown state, a maintenance instruction is triggered (usually triggered by a maintenance key), and the generator set enters a maintenance state; when a maintenance key is used for a wind turbine generator in a standby state, the fan enters a maintenance state after 3 seconds of delay; when a maintenance key is used for a maintenance position of the running wind turbine generator, the wind turbine generator firstly enters a shutdown state, enters a standby state after the wind turbine generator is shut down for 45 seconds, and enters a maintenance state after 3 seconds of delay; the fan in the maintenance state does not allow automatic yawing, and manual yawing can be performed.
Further, the environmental parameters include: an ambient temperature value, an ambient humidity value, and an ambient brightness value.
Specifically, because the wind turbine generator generates different heat at different operation stages, and because of the change of the external environment, the operation mode of the temperature adjusting equipment is different when the temperature is adjusted, so that the environmental temperature value of the environment where the temperature adjusting equipment is located needs to be referred to when the temperature adjusting equipment is controlled; similarly, the control of the humidity control device and the lighting device is also affected by the external environment, and therefore, an environment humidity value and an environment brightness value need to be acquired.
Further, based on the operating state of the wind turbine generator, determining the switching state of each electric device includes:
if the running state of the wind turbine generator is a shutdown state or a standby state, determining that the temperature adjusting equipment, the humidity adjusting equipment and the lighting equipment are in an equipment cutting state;
if the running state of the wind turbine generator is any one of a starting state, a grid-connected state and a shutdown process, determining that the lighting equipment is in an equipment cut-off state, and the temperature regulating equipment and the humidity regulating equipment are in an equipment input state;
and if the running state of the wind turbine generator is the maintenance state, determining that the temperature adjusting equipment and the humidity adjusting equipment are in the equipment cutting state, and the lighting equipment is in the equipment putting-in state.
Specifically, when the wind turbine generator is in a shutdown state and a standby state, the number of devices in operation per se is small, the rotating speed of the impeller is low, and the heat generated by the temperature generated per se (such as rotation of a bearing and electric work) is limited, at the moment, the temperature can be reduced through self heat dissipation, and temperature adjustment, humidity adjustment and illumination are not needed; when the wind turbine generator is in a grid-connected state, the generated heat reaches a peak value when the wind turbine generator is in a power generation state, and temperature regulation must be carried out through temperature regulation equipment; when the wind turbine generator is in a shutdown process, the rotating speed of the impeller is slowly reduced, and although the newly increased heat production amount is reduced, the wind turbine generator also has certain waste heat and also needs temperature adjusting equipment to adjust the temperature. Finally, when the wind turbine generator is in a maintenance state, the wind turbine generator works, and the generated heat is less, so that the temperature adjusting equipment and the humidity adjusting equipment are in an equipment cutting state, but in order to facilitate the access of maintainers to the inside of the fan for maintenance, the lighting equipment is set to be in an equipment putting-in state, and the lighting brightness is improved.
In another embodiment, in order to guarantee the operation safety of the wind turbine generator, no matter which operation state the wind turbine generator is in, the fire protection equipment and the monitoring equipment are set to be in an equipment input state at all times, so that the fire can be timely extinguished through the fire protection equipment when the wind turbine generator is in a fire. The monitoring equipment can acquire internal sound and video monitoring information to realize remote monitoring and storage in the control room, and carry out fault analysis based on the collected sound information and video information to judge whether the wind turbine generator set is abnormal, so that the fireproof equipment and the monitoring equipment need to work in real time.
Further, the first type of self-powered equipment is temperature regulating equipment; determining the equipment operation limit value of the first type of self-powered equipment in the equipment input state based on the wind turbine generator operation state and the environmental parameters, wherein the method comprises the following steps:
if the running state of the wind turbine generator is the starting state and the environmental temperature value of the temperature regulating equipment is greater than the preset temperature value, determining that the equipment running limit value of the temperature regulating equipment is first preset power, and if the running state of the wind turbine generator is the starting state and the environmental temperature value of the temperature regulating equipment is less than or equal to the preset temperature value, determining that the equipment running limit value of the temperature regulating equipment is second preset power;
if the running state of the wind turbine generator is a grid-connected state and the ambient temperature value of the temperature regulating equipment is greater than a preset temperature value, determining that the equipment running limit value of the temperature regulating equipment is a third preset power, and if the running state of the wind turbine generator is a grid-connected state and the ambient temperature value of the temperature regulating equipment is less than or equal to the preset temperature value, determining that the equipment running limit value of the temperature regulating equipment is a first preset power;
if the running state of the wind turbine generator is a shutdown process and the environmental temperature value of the temperature regulating equipment is greater than a preset temperature value, determining that the equipment running limit value of the temperature regulating equipment is fourth preset power, and if the running state of the wind turbine generator is a shutdown process and the environmental temperature value of the temperature regulating equipment is less than or equal to the preset temperature value, determining that the equipment running limit value of the temperature regulating equipment is second preset power;
the third preset power is greater than the fourth preset power, the fourth preset power is greater than the first preset power, and the first preset power is greater than the second preset power.
Specifically, because the wind turbine generator system is the most heat that produces when being incorporated into the power networks the state, self heat production increases gradually when being in the starting condition, when being in the shutdown process, although the heat production of newly-increased is few, but, the waste heat is more, consequently, all need carry out temperature regulation through attemperator, with the help wind turbine generator heat dissipation, in order to guarantee that wind turbine generator system work is under normal temperature, but, because there is the difference in the ambient temperature that wind turbine generator system located (like annual different seasons with, different hours and different weather every day, make ambient temperature all have the difference), consequently, need combine wind turbine generator system to control under different running state and different ambient temperature.
When the wind turbine generator is in a starting state and an environment temperature value of the temperature regulating equipment is greater than a preset temperature value (if the environment temperature is relatively high in noon), determining that an equipment operation limit value of the temperature regulating equipment is first preset power, and if the wind turbine generator is in a starting state and the environment temperature value of the temperature regulating equipment is less than or equal to the preset temperature value (if the environment temperature is relatively low in the morning), determining that the equipment operation limit value of the temperature regulating equipment is second preset power;
similarly, when the operation state of the wind turbine generator is a grid-connected state, the heat generated by the wind turbine generator reaches a peak value, the ambient temperature value of the temperature regulating device is greater than a preset temperature value (if the ambient temperature is at noon, the ambient temperature is relatively high), the wind turbine generator cannot realize heat dissipation through natural heat dissipation, auxiliary heat dissipation through the temperature regulating device is needed, the device operation limit value is set to be third preset power under the condition, if the ambient temperature value of the temperature regulating device is less than or equal to the preset temperature value (if the ambient temperature is at morning, the ambient temperature is relatively low), but the heat generated by the wind turbine generator is relatively large, the device operation limit value of the temperature regulating device needs to be set to be first preset power, and the third preset power is greater than the first preset power.
Similarly, when the running state of the wind turbine generator is the shutdown state, heat generation of the wind turbine generator is reduced, but a certain amount of waste heat exists, and heat is also dissipated by the temperature adjusting device in an auxiliary manner, if the ambient temperature value of the temperature adjusting device is greater than a preset temperature value (if the ambient temperature is higher in the noon), the device running limit value of the temperature adjusting device is set as fourth preset power, and if the ambient temperature value of the temperature adjusting device is less than or equal to the preset temperature value (if the ambient temperature is lower in the morning), the device running limit value of the temperature adjusting device is set as second preset power, and the fourth preset power is greater than the second preset power. More specifically, the operating limits of the tempering device are: the third preset power is greater than the fourth preset power, the fourth preset power is greater than the first preset power, and the first preset power is greater than the second preset power.
Further, the second type of self-powered equipment is humidity control equipment; determining the equipment operation limit value of the second type of self-powered equipment in the equipment putting state based on the environmental parameters, wherein the method comprises the following steps:
if the humidity value of the environment where the humidity control equipment is located is smaller than a preset humidity value, determining that the equipment operation limit value of the humidity control equipment is a fifth preset power;
if the humidity value of the environment where the humidity control equipment is located is larger than or equal to a preset humidity value, determining that the equipment operation limit value of the humidity control equipment is a sixth preset power;
the fifth preset power is smaller than the sixth preset power.
Specifically, the humidity of the environment of the wind turbine generator is too high, corrosion of the wind turbine generator is accelerated, and the service life of the wind turbine generator is reduced, so that the humidity of the environment in the wind turbine generator is adjusted in an auxiliary manner by the humidity adjusting device, but the humidity of the environment in the wind turbine generator is changed along with the humidity of the environment in the natural environment, so that the humidity of the environment in the wind turbine generator is greater than or equal to a preset humidity value after the weather such as rain, the humidity of the environment in the wind turbine generator is reduced by the humidity adjusting device, the humidity of the environment in the wind turbine generator is likely to increase, therefore, the humidity adjusting device needs to be operated in a high-power state all the time, the power consumption is greatly increased, but the humidity of the environment in the wind turbine generator is likely to be higher than the preset humidity value, so that the humidity adjusting device is operated at a sixth preset power to prevent the humidity of the environment in the wind turbine generator from continuously increasing until the humidity of the environment in the humidity adjusting device is smaller than the preset humidity value, and adopting a fifth preset power to work so as to reduce the working power of the humidity control equipment, thereby reducing the power consumption, wherein the fifth preset power is smaller than the sixth preset power.
Further, the second type of self-powered device is a lighting device; determining the equipment operation limit value of the second type of self-powered equipment in the equipment putting state based on the environmental parameters, wherein the method comprises the following steps:
if the brightness value of the environment where the lighting equipment is located is smaller than a preset brightness value, determining that the equipment operation limit value of the lighting equipment is a seventh preset power;
if the brightness value of the environment where the lighting equipment is located is greater than or equal to a preset brightness value, determining that the equipment operation limit value of the lighting equipment is eighth preset power;
the seventh preset power is greater than the eighth preset power.
Specifically, when the wind turbine generator is in the maintenance state, it may be the time when the external brightness is low in the morning and evening and the brightness is high in the midday, so when the wind turbine generator enters the maintenance state, the power control is performed according to the ambient brightness value of the lighting device, including setting a seventh preset power and an eighth preset power, where the seventh preset power is greater than the eighth preset power; if the brightness value of the environment where the lighting equipment is located is smaller than the preset brightness value, it is indicated that the environment is dark, and a seventh preset power with a larger power is adopted for the equipment operation limit value of the lighting equipment; if the brightness value of the environment where the lighting device is located is greater than or equal to the preset brightness value, it indicates that the environment is bright, and the brightness generated by the lighting device may be appropriately reduced, so the device operation limit of the lighting device may be set to the eighth preset power.
