Description

Technical Field

[0001] This utility model relates to the field of power generation equipment monitoring technology, specifically to a visual status monitoring device for generator sets. Background Technology

[0002] In today's rapidly developing power industry, the monitoring of the operating status of hydro-turbine generator units, as key equipment in hydropower stations, is particularly important. Traditional operating status indications for hydro-turbine generator units typically rely on turbine headlights or ring indicator lights, which visually reflect the unit's operating status, such as standby, no-load, idle, and grid connection, through the on / off state and color changes of the lights. However, with the increasing demand for refined management of unit operating status in power systems, traditional indication methods are gradually revealing their inherent limitations.

[0003] First, traditional indicator lights can only display limited status information and cannot comprehensively reflect the detailed operating parameters of the unit, such as terminal voltage, current, speed, guide vane opening, head, water level, flow rate, and vibration swing. This means that operators cannot obtain more specific details about the unit's operation from these simple light signals, reducing the accuracy and efficiency of judging the unit's status. Second, traditional headlights or ring indicator lights lack diversity, and their display forms and content are relatively simple, failing to adapt to the information needs of different working scenarios. For example, in situations such as unit maintenance, important event reception, and safety production promotion, traditional indicator lights cannot provide additional information display functions, limiting their application value in specific contexts. Furthermore, the aesthetics of traditional indicator lights also have room for improvement. They are usually designed with functionality as the priority, without much consideration for the coordination and aesthetics with the entire generator set, which to some extent affects the overall image and appearance of the power station.

[0004] In summary, existing turbine generator headlights or ring indicator lights have significant shortcomings in terms of functionality, information display capacity, applicable scenarios, and aesthetics, failing to meet the high standards of modern power systems that demand refined management of generator operation status and diverse information needs. Therefore, there is an urgent need for a new type of display device that not only provides intuitive indications of generator operation status but also displays detailed operating parameters, flexibly switches display content in different scenarios, and enhances the overall aesthetics of the generator set. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems by providing a generator set visual status monitoring device. This device employs an information zoning approach, using intuitive color and information displays to enable operators to quickly and accurately understand the generator set's operating status, thereby improving equipment management efficiency, enhancing the device's functionality, and expanding its applicability.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A generator set visual status monitoring device includes a generator set, the generator set including a generator head, the generator head being provided with a display component, the display component including a color display module for displaying indicator colors and an information display module for displaying indicator information; it also includes a monitoring module and a control module for detecting the operating status of the generator set, the monitoring module acting on the generator, and the signals of the monitoring module and the display component being connected to the control module, the control module being able to send control commands to the display component based on the monitoring data values ​​transmitted by the monitoring module.

[0008] By adopting the above technical solution, the monitoring module collects the generator set's operating data, and the control module analyzes the data and determines the displayed content and colors, thereby achieving a visual representation of the status. During generator set operation, the operator can quickly visually identify the overall status of the generator set through the color display module, such as standby, no-load, idle, grid-connected, transition, and abnormal status. At the same time, the operator can obtain detailed operating parameters and indication information through the information display module, facilitating timely implementation of corresponding measures to ensure the safe and stable operation of the unit.

[0009] Furthermore, the control module includes a signal receiving module, an operating status judgment module, an information buffer module, and an information sending module. The monitoring module is signal-connected to the signal receiving module, the signal receiving module is signal-connected to the operating status judgment module, the operating status judgment module is signal-connected to the color display module and the signal buffer module, the signal buffer module is signal-connected to the information sending module, and the information sending module is signal-connected to the information display module.

[0010] Thanks to the above technical solution, during the operation of the generator set, the signal receiving module receives monitoring data values ​​from the monitoring module, the operating status judgment module analyzes the data and judges the status, and the color display module provides color indication. At the same time, the information cache module stores the information to be displayed, and the information sending module sends the information stored in the information cache module to the information display module in real time. This achieves efficient data flow and status feedback, reduces system response delay, and ensures that operators can obtain key information in a timely manner.

[0011] Furthermore, the control module also includes an alarm module, which is connected to the operating status judgment module and the information display module respectively.

[0012] Thanks to the above technical solution, when the monitoring data indicates an abnormal state during the operation of the generator set, the alarm module is triggered and outputs alarm information through the information display module. The operator can immediately identify the problem and take quick countermeasures to prevent the fault from escalating or the equipment from being damaged.

[0013] Furthermore, the operating status judgment module can determine that the generator set is in multiple operating states based on the monitoring data values, and each operating state corresponds to a color in the color display module.

[0014] Thanks to the above technical solution, during the operation of the generator set, the operating status judgment module classifies the generator set status into multiple working states based on real-time monitoring data values ​​and maps them to specific colors of the color display module. Operators can intuitively identify the current status by color changes, simplifying the monitoring process and improving decision-making speed.

[0015] Furthermore, the machine head is provided with a slip ring chamber, and the display component is located in the slip ring chamber.

[0016] Thanks to the above technical solution, the display components are directly installed in the slip ring chamber of the generator head during generator operation. Operators can directly view the status information of the color display module and the information display module without moving or using additional equipment during inspection or operation, which improves the convenience of monitoring and the efficiency of on-site operation.

[0017] Furthermore, the color display module is a colored light strip arranged circumferentially in the slip ring chamber.

[0018] Thanks to the above technical solution, during the operation of the generator set, the color display module adopts a color light strip design that is circumferentially arranged in the slip ring chamber, providing 360-degree all-round visible light indication. Even at a distance or in poor lighting conditions, the operator can clearly identify the working status represented by the color change, enhancing visual recognition and safety.

[0019] Furthermore, the information display module is a display screen arranged circumferentially in the slip ring chamber.

[0020] Thanks to the above technical solution, during the operation of the generator set, the information display module is a display screen that is circumferentially mounted in the slip ring chamber, displaying detailed text or graphic instructions. The operator can obtain specific data from any angle, supporting rapid decision-making and fault diagnosis, and avoiding information omissions.

[0021] Furthermore, the slip ring chamber is provided with an assembly groove, the display component is disposed in the assembly groove, and the assembly groove is provided with an openable and closable protective cover.

[0022] Thanks to the above technical solution, during generator set operation, the display components are installed in the assembly slot of the slip ring chamber. The assembly slot is equipped with an openable protective cover to protect the color display module and information display module from dust, moisture or mechanical damage. It is easy to open for cleaning or replacement during maintenance, extending the equipment life and ensuring display clarity.

[0023] Furthermore, the monitoring module includes a generator outlet sensing module for monitoring the generator set outlet operating status and / or a rotor sensing module for monitoring the generator set rotor operating status and / or an operating sensor module for monitoring the generator set operating status. The generator outlet sensing module transmits voltage data values, current data values, and generator outlet circuit breaker status data values ​​to the control module. The rotor sensing module transmits rotor speed data values ​​to the control module. The operating sensor module transmits generator set vibration data values ​​to the control module.

[0024] Thanks to the aforementioned technical solution, each sensor module transmits the monitored data to the control module in real time, and the control module then performs corresponding display and control actions based on the data. This multi-dimensional monitoring improves the accuracy and comprehensiveness of status assessment, helping to promptly identify potential problems.

[0025] Furthermore, the generator set is a hydro-generator, and the monitoring module also includes a guide vane opening sensing module and / or a head monitoring module and / or a water level monitoring module. The guide vane opening sensing module transmits guide vane opening data values ​​to the control module, the head monitoring module transmits working environment head data values ​​to the control module, and the water level monitoring module transmits working environment water level data values ​​to the control module.

[0026] Thanks to the above technical solution, during the operation of the generator set, the monitoring module collects guide vane opening data through the guide vane opening sensor module, ambient head data through the head monitoring module, and ambient water level data through the water level monitoring module. These sensors transmit the monitored data to the control module, which adjusts the display content based on the data, thereby achieving precise monitoring of the generator's operating status. Operators can more accurately grasp the generator's operating condition, which helps improve operating efficiency and safety.

[0027] In summary, due to the adoption of the above technical solutions, the beneficial effects of this utility model are as follows: By employing an information zoning approach and using intuitive color and information displays, operators can quickly and accurately understand the operating status of the generator set, improving equipment management efficiency.

[0028] Figure 1 This is a schematic diagram of the structure of the generator set visual status monitoring device of this utility model;

[0029] Figure 2 This is a flowchart of the operation of the generator set visual status monitoring device of this utility model.

[0030] The markings in the diagram are: 1-slip ring chamber, 101-assembly slot, 2-information display module, and 3-color display module. Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] Example 1

[0034] like Figure 1 As shown, the generator set visualization status monitoring device in this embodiment mainly consists of several key components, including a slip ring chamber 1, an information display module 2, and a color display module 3. The slip ring chamber 1 is one of the core structures of the device, and it is equipped with an assembly slot 101 for fixing and accommodating the display components. Among the display components, the information display module 2 is responsible for presenting detailed operating information, while the color display module 3 uses different colors to intuitively reflect the working status of the generator set. The two work together to enable operators to quickly obtain important feedback on the generator set's operating status.

[0035] The control module is the brain of this visual status monitoring device. It includes a signal receiving module, an operating status judgment module, an information buffering module, an information sending module, and an alarm module. The signal receiving module receives data from the monitoring module, which may include key parameters such as voltage, current, rotor speed, vibration, guide vane opening, and ambient water head and level. The operating status judgment module determines the generator set's operating status based on the received monitoring data, such as common operating conditions like standby, no-load, idle, grid connection, transition, and fault. Each status corresponds to a specific color in the color display module 3.

[0036] The information caching module temporarily stores received monitoring data, ensuring that information is not lost even when the network is unstable or processing is delayed. The information sending module organizes the cached information and sends it to the information display module 2 for operators to view detailed data. The alarm module is connected to the information display module 2. Once the operating status judgment module detects a data value exceeding a preset safety range, the alarm module is activated. The alarm module sends an alarm data value to the information display module 2, and the display component interrupts its current display, prioritizing the alarm information and displaying it immediately. In another embodiment, in addition to sending alarm data values ​​to the information display module 2, the alarm module can also trigger an alarm to alert operators to take necessary countermeasures via sound.

[0037] The color display module 3 is surrounded by a circumferentially arranged ring of colored lights. This layout ensures that the color changes are clearly visible from any angle, allowing for real-time access to generator status information. The information display module 2 also uses a ring-shaped display screen, capable of displaying more detailed information such as specific voltage, current, and rotor speed, aiding operators in in-depth analysis. The color display module 3 is positioned side-by-side with the information display module 2, above it, ensuring that operators notice the color display module 3 first, and then access the information from the information display module 2 as needed. The mounting slot 101 on the slip ring chamber 1 ensures the display components are securely installed. A transparent protective cover is provided at the mounting slot 101; this cover can be opened and closed, facilitating installation and maintenance, and effectively protecting the display components from external environmental factors such as dust and moisture during normal use, thus extending their lifespan. The outer surface of the protective cover is flush with the outer ring of the slip ring chamber 1, further enhancing safety. The color display module 3 can be an LED color ring, and the information display module 2 can be a flexible display screen that can be bent to a certain degree of curvature.

[0038] The monitoring module includes, but is not limited to, a generator outlet sensing module, a rotor sensing module, and an operation sensor module. For specific applications such as hydro-generators, it may also include a guide vane opening sensing module, a head monitoring module, and a water level monitoring module. The generator outlet sensing module monitors the generator set's outlet operating status, providing data such as voltage, current, and generator outlet circuit breaker status. The rotor sensing module monitors the rotor speed, while the operation sensor module focuses on the overall vibration of the generator set. In hydro-generator applications, the guide vane opening sensing module monitors the guide vane opening, while the head and water level monitoring modules detect head and water level data under the operating environment, respectively. All this data is processed and analyzed by the control module to provide operators with comprehensive and real-time generator set status reports.

[0039] For example, when the voltage and current data values ​​transmitted by the generator outlet sensor module are both 0 or close to 0, the generator outlet circuit breaker is in the open state, the rotor speed data value transmitted by the rotor sensor module is 0 or close to 0, and the guide vane opening data value transmitted by the guide vane opening sensor module is 0, the operation status judgment module determines that the generator set is in standby mode, the color display module 3 displays blue, and the information display module 2 can display the current status of the generator set, celebration information, safe production days, welcome message, custom image, and other set information. When the voltage data value transmitted by the generator outlet sensor module reaches the rated voltage value, the current data value is close to 0, the generator outlet circuit breaker is in the open state, the rotor speed data value transmitted by the rotor sensor module reaches the rated speed value, and the guide vane opening data value transmitted by the guide vane opening sensor module is not 0, the operation status judgment module determines that the generator set is in no-load mode, the color display module 3 displays yellow, and the information display module 2 can display the current status of the generator set, celebration information, safe production days, welcome message, custom image, and other set information. If the generator output sensor module transmits voltage data that does not reach the rated voltage value, current data that is close to 0, and the generator output circuit breaker is in the open state, while the rotor sensor module transmits rotor speed data that reaches the rated speed value, and the guide vane opening sensor module transmits guide vane opening data that is not 0, then the operating status judgment module determines that the generator set is in an idling state. The color display module 3 displays orange, and the information display module 2 can then display the generator set's current status, voltage data value, celebration information, number of safe production days, welcome message, custom image, and other set information. If the generator output sensor module transmits voltage data that is consistent with the grid voltage, current data that is positively correlated with output power, the generator output circuit breaker is in the closed state, the rotor sensor module transmits rotor speed data that is at the rated speed value, and the guide vane opening sensor module transmits guide vane opening data that is dynamically adjusted according to the actual load, then the operating status judgment module determines that the generator set is in a grid-connected state. The color display module 3 displays green, and the information display module 2 can then display the generator set's current status, current data value, guide vane opening data value, and other set information. The voltage, current, and generator outlet circuit breaker data values ​​transmitted by the generator outlet sensing module, the rotor speed data value transmitted by the rotor sensing module, and the guide vane opening data value transmitted by the guide vane opening sensing module are dynamically changing according to the transition operation. When the generator set vibration data value increases, the operating status judgment module determines that the generator set is in a transition state. The color display module 3 displays purple, and the information display module 2 can display the current status of the generator set and the relevant data values ​​involved in the current transition operation.If any of the voltage data value, current data value, rotor speed data value, generator set vibration data value, working environment water head data value, or working environment water level data value transmitted by the generator outlet sensor module exceeds the safety threshold, the operating status judgment module determines that the generator set is in an abnormal state. The color display module 3 displays it in red, and the information display module 2 can then display the current status of the generator set and the relevant data values ​​of the current abnormal state.

[0040] The generator set visualization status monitoring device provided in this embodiment significantly improves operators' perception and response speed regarding the generator set's operating status by combining intuitive color displays, detailed information displays, and an instant alarm mechanism, thereby enhancing equipment management and maintenance efficiency. Furthermore, comprehensive monitoring of key operating parameters ensures the generator set's efficient, safe, and stable operation, reducing failure rates and downtime caused by equipment problems, ultimately improving the overall performance and economic benefits of the generator set. This innovative design is not only applicable to hydroelectric generators but can also be applied to other types of power generation equipment, demonstrating broad applicability and promising prospects for widespread adoption.

[0041] In this embodiment, the generator set visualization status monitoring device first collects real-time operating data of the generator set from various sensors in the monitoring module, including but not limited to voltage, current, speed, guide vane opening, head, and water level. This data is transmitted to the signal receiving module of the control module via signal lines. Upon receiving the data, the signal receiving module sends it to the operating status judgment module and the information cache module. The operating status judgment module analyzes the data according to preset rules and thresholds, determines the current operating status of the generator set, and controls the color display module to display the corresponding color. Simultaneously, the information cache module stores detailed information to be displayed, such as operating parameters and warning messages. The information sending module sends this information to the information display module according to control commands, displaying it statically or in a scrolling manner. Throughout the operation, if an anomaly is detected, the alarm module is immediately activated, instantly interrupting the display of other information and displaying the alarm message on the information display module 2. This process enables real-time, comprehensive, and intuitive monitoring and display of the generator set's operating status, greatly improving the efficiency and safety of operation management.
