What the data for this category looks like
Data sources for wind power revenue yield and market daily reports include public power trading settlement platform APIs, wind turbine SCADA IoT interfaces, and meteorological monitoring data interfaces. Data updates follow a fixed schedule: full updates are completed at set daily times, and real-time running data refreshes every 5 minutes. The daily report aggregates full grid-connected settlement data from the previous day, and is updated only once per day. Each data entry uses a structured format, with fields including wind farm code, statistical date, daily grid-connected power generation, daily trading settlement electricity price, unit installed operation and maintenance cost, subsidy calculation amount, and daily total revenue. The units for these fields are, respectively: code, date, kilowatt-hour, yuan per kilowatt-hour, yuan per installed kilowatt, yuan, yuan.
What constraints these characteristics impose on workflow orchestration
Multiple data sources have different interface authentication methods. The workflow must connect multiple different types of API nodes, and corresponding authentication parameters must be configured separately. The fixed-time daily report update requires a scheduled trigger node in the workflow. The trigger time must be later than the data update completion time to avoid pulling incomplete data. Structured data with multiple fields requires a data cleaning node to filter invalid fields and abnormal values. Otherwise, the accuracy of revenue yield calculation will be affected. High data timeliness requirements: if data is not obtained within the timeout period, the daily report will be delayed. A timeout retry and alert mechanism must be configured. Minor differences exist in data formats across different wind farms. A unified field mapping rule must be configured to ensure cross-farm data can be combined for calculation.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
Scheduled Task Trigger Time | 04:30 Daily | Wind power daily report data usually completes full updates before 04:00, reserving 30 minutes of buffer time to ensure complete data |
HTTP Request Timeout | 600 Seconds | Multi-interface serial requests involve large data volumes, avoiding task failure due to network latency or slow interface responses |
Field Mapping Rule | Associate each interface data by wind farm ID | Different interface return data uses wind farm ID as the unique identifier, and unified association is required to complete revenue yield calculation |
Failure Retry Count | 3 Times | Temporary fluctuations may occur in power data interfaces, and multiple retries can reduce task failure rates |
Null Value Handling Strategy | Skip rows containing null values and write error logs | Wind power data may include unreported operation and maintenance cost data, requiring filtering of invalid data |
Node Execution Order | Pull meteorological data first → then pull trading data → finally pull wind farm operation data | Revenue yield calculation requires core data of electricity price and power generation first, so the execution order cannot be reversed |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require on-site analysis, and it is recommended to test on your own samples before finalizing the settings.
Three Common Mistakes
- A large number of blank lines appear in the daily report data generated after workflow execution. The cause is that the
Null Value Handling Strategyis not configured, and the original data containing null values returned by the interface is retained directly. - A
429 Too Many Requestserror pops up during execution. The cause is that a reasonableFailure Retry Countis not set, and the request frequency exceeds the current limiting threshold of the power data interface. - The AI chat node cannot obtain the output content of the workflow. The cause is that the output variable of the workflow is not bound to the context variable of the AI node, or the variable mapping priority is set incorrectly.
How to confirm the configuration is correct
- Manually trigger the workflow, check whether there is a record of
Scheduled Task Trigger Successfulin the execution log, and confirm that the trigger time configuration meets expectations. - Check the output result of the data cleaning node, confirm that rows containing null values have been filtered out, and that the field names match the preset revenue yield calculation rules.
- View the context variable configuration of the AI chat node, confirm that the output variable of the workflow has been bound, and that the variable mapping order is set reasonably.
- Wait for the next day's scheduled trigger to complete, confirm that the daily report data is fully generated, and that there are no
429or timeout-related error logs.
