What the data for this category looks like
Wind power revenue yield-related data is primarily sourced from station metering systems and provincial power grid settlement platforms. Full data for the previous calendar day is generated by 02:00 each day. Data documents use a structured table format, with each record corresponding to the daily operation and revenue status of a single wind farm. Fields include station unique code, statistical date, total power generation, grid-connected power generation, grid settlement unit price, allocated operation and maintenance costs, and daily revenue calculation amount. Corresponding units for each field are: megawatt-hours, date in YYYY-MM-DD format, megawatt-hours, megawatt-hours, yuan per megawatt-hour, yuan, yuan. No custom percentage-based calculation fields are included.
What constraints these characteristics impose on HTTP Interfaces and External Systems
Wind power revenue yield data must integrate with two separate external systems: station metering and grid settlement. Interfaces must support multi-source data aggregation and verification. The fixed daily update schedule requires configuring reasonable timeout settings for interfaces, to avoid overall task failure due to single-source response delays. Structured fields have individual differences at the station level, so interfaces must support custom field mapping rules. Data involves sensitive grid settlement information, so interfaces must integrate signature verification and IP whitelist configuration options. Cross-region station data pulling may cause network delays, so exponential backoff retry strategies must be configured.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
external_api_timeout | 600 seconds | Wind power data pulling aggregates two independent data sources; a 10-minute timeout accommodates total multi-source response latency |
field_mapping_enable | Enabled | Wind farm stations have individual field differences; custom mapping rules are required to match business requirements |
signature_auth_type | HMAC-SHA256 | Grid settlement data is sensitive; HMAC signature meets interface security verification requirements |
retry_strategy | Exponential backoff, maximum 3 retries | Cross-region station pulling has network fluctuations; backoff strategies reduce resource consumption from repeated requests |
daily_sync_time | 03:00 | Grid data is fully updated by 02:00; a 1-hour processing window is reserved for daily data synchronization |
file_parse_format | CSV structured parsing | Wind power data documents use standard CSV format; structured parsing improves field extraction accuracy |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- An interface returns
400 Bad Requestwith the prompt "field format not supported". This occurs when thefield_mapping_enableswitch is not configured, and the default field mapping rule is used directly without adapting to individual station field differences. - A scheduled synchronization task times out and fails, with the log showing
request timeout. This occurs whenexternal_api_timeoutis set too short, failing to accommodate cross-region response delays for multi-source data pulling. - An interface call returns
403 Forbidden. This occurs whensignature_auth_typeand IP whitelist are not configured, and the grid settlement interface rejects unauthorized access requests.
How to Verify Successful Configuration
- Call the test interface to pull a single piece of wind power data, and verify that the returned fields match the configured field mapping rules.
- Check the scheduled task execution logs to confirm that full data pulling is completed after the configured synchronization time, with no timeout errors.
- Send an interface request with a valid signature, and confirm that the returned status code is
200 OKwith no authorization-related errors. - Simulate a network delay scenario, trigger the retry strategy, and confirm that the task completes successfully with no data loss.
