Description

Technical Field

[0001] The utility model relates to the technical field of automatic water regime measurement and reporting, in particular to an automatic water regime measurement and reporting system for a pumped storage power station. Background Art

[0002] The automatic water regime monitoring and reporting system is an information system that uses telemetry, communication, computer and network technologies to automatically collect, transmit, process and apply water regime elements. In order to ensure the safe operation of the pumped storage power station and the safety of downstream flood control, the power station needs to be equipped with an automatic water regime monitoring and reporting system. In the initial stage of operation, a rainfall runoff forecasting plan is formed to forecast and calculate the flood inflow process of the reservoir downstream of the power station, so as to provide a decision-making basis for the safe operation of the power station, flood control, reservoir scheduling and rational use of water resources. The automatic water regime monitoring and reporting system needs to provide reliable, real-time and continuous water regime data, including: water levels of the upper and lower reservoirs; inflow flow; outflow flow; precipitation; gate opening and other elements, and send them to the group company's water regime monitoring and reporting system and various water conservancy and environmental protection departments.

[0003] At present, in the engineering practice of pumped-storage power stations, some power stations use wired communication methods or mobile public network communication methods to transmit water conditions data between telemetry stations and central stations.

[0004] However, the wired communication method is expensive and due to geographical restrictions, there are fewer water sensors deployed, which cannot provide sufficient water data; the mobile public network communication method will cause water data transmission to be interrupted when communication equipment fails. Therefore, the reliability, real-time and accuracy of water data cannot be guaranteed. Utility Model Content

[0118] A solar cell power source (105) and a battery power source (106).

[0122] Based on the above embodiment, a method for automatic water regime monitoring and reporting of a pumped storage power station is also provided, which can be applied to the automatic water regime monitoring and reporting system of the above pumped storage power station. Figure 5 , Figure 5 A schematic flow chart of a method for automatically measuring and reporting water conditions in a pumped storage power station provided in one embodiment of the present application. The method for automatically measuring and reporting water conditions in a pumped storage power station specifically includes:

[0123] S501: The water condition sensor collects water condition data and sends the water condition data to the water condition data collection controller.

[0124] Among them, water conditions data include: rainfall data, water level data, flow data and meteorological data.

[0125] In this embodiment, the water condition sensor automatically collects water condition data and sends the collected real-time water condition data to the data acquisition controller to ensure that the water condition data is obtained in a timely manner and stored.

[0126] S502: The water regime data collection controller determines all water regime data that meet preset reporting conditions as reported water regime data.

[0127] Specifically, the preset reporting conditions are: the incremental data in the water condition data reaches the incremental threshold; or the water condition data reporting interval reaches the time threshold.

[0128] Optionally, the incremental data may be a rainfall increment or a water level increment, and different incremental data correspond to different incremental thresholds.

[0129] Optionally, the reporting interval can be remotely set by the operating personnel through the workstation of the central station, and the reporting interval can be set to 24h, 12h, 8h, 6h, 3h or 1h.

[0130] In this embodiment, when the rainfall increases by 0.5 mm, it exceeds the incremental threshold, the accumulated rainfall automatically increases by 0.5 mm, and is determined as reported water situation data; when the water level changes by 1 cm, it exceeds the incremental threshold, the real-time water level after the change is automatically collected, and is determined as reported water situation data.

[0131] S503: The water condition data collection controller reports the water condition data and sends it to the second satellite communication terminal via the first satellite communication terminal and the Beidou satellite system; or the water condition data collection controller reports the water condition data and sends it to the second mobile communication device via the first mobile communication device.

[0132] S504: The second satellite communication terminal or the second mobile communication device sends the reported water condition data to the data collection server.

[0133] S505: If the data acquisition server determines that the reported water condition data does not need to be verified and the measurement frequency does not need to be changed, the reported water condition data is sent to the first network configuration station or the second network configuration station.

[0134] In this example, if data verification is required, or the measurement frequency needs to be changed: if the data acquisition server determines that the reported water condition data needs to be verified, a call for measurement instruction is generated; if the data acquisition server determines that the reported water condition data needs to be changed in the measurement frequency, and detects the user's editing operation, a water condition query instruction is generated in response to the user's editing operation; the data acquisition server sends the call for measurement instruction and / or the water condition query instruction to the first satellite communication terminal via the second satellite communication terminal and the Beidou satellite system; or the water condition data acquisition controller sends the call for measurement instruction and / or the water condition query instruction to the first mobile communication device via the second mobile communication device; the first satellite communication terminal or the first mobile communication device sends the call for measurement instruction and / or the water condition query instruction to the water condition data acquisition controller; the water condition data acquisition controller sends the call for measurement instruction and / or the water condition query instruction to the water condition sensor; the water condition sensor re-collects water condition data according to the call for measurement instruction and / or the water condition query instruction.

[0135] S506: The first network configuration station or the second network configuration station sends the reported water condition data to the computer monitoring system.

[0136] S507: The computer monitoring system obtains the data to be operated according to the reported water condition data; wherein the data to be operated is to adjust the operating parameters of the pumped storage power station corresponding to each water condition telemetry station.

[0137] In this embodiment, the pumped storage power station can be a daily regulation pure pumped storage power station with an installed capacity of 1200MW and an average power generation of 1.2 billion kW·h over many years. The main development task is power generation, and it undertakes the tasks of peak regulation, valley filling, frequency regulation, phase regulation and standby of the provincial power grid. The basin where the power station is located has a mid-subtropical marine climate with distinct four seasons, warm and humid weather and abundant rainfall. The runoff in the basin mainly comes from rainfall, which is unevenly distributed throughout the year, mostly concentrated in March to September, and floods mostly occur in April to September.

[0138] Optionally, the data to be operated may be the operating parameters for adjusting the above-mentioned daily regulation pure pumped storage power station.

[0139] It can be seen from the above embodiments that the automatic collection of water condition data from multiple telemetry stations can be realized by presetting reporting conditions; the reported water condition data that meets the preset reporting conditions is sent to the second satellite communication terminal via the first satellite communication terminal and the Beidou satellite system; or the reported water condition data is sent to the second mobile communication device via the first mobile communication device. On the one hand, it can avoid the problem of limiting the deployment of water condition sensors due to cost and geographical conditions; on the other hand, setting the main communication channel and the backup communication channel can avoid the problem of communication interruption when a single communication channel fails. Thereby improving the reliability, real-time and accuracy of water condition data. In addition, the automatic water condition measurement and reporting system of the pumped storage power station also includes a first network configuration station and a second network configuration station. The first network configuration station and the second network configuration station are hot standby for each other, ensuring that after the central station receives the reported water condition data, it can avoid the problem of data transmission interruption when equipment failure occurs in the network configuration center; it can further improve the reliability, real-time and accuracy of water condition data.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
