What the Data for This Category Looks Like
Data sources for power grid equipment-related yield and market data include regional power trading center grid-connected equipment revenue ledgers, real-time operating data from power IoT monitoring platforms, and public equipment asset archives from national power grid operators. Update frequencies vary across sources: real-time operating parameters update every minute. Grid-connected revenue data updates per calendar day. Asset ledger data updates quarterly. Most documents use structured JSON or CSV formats, with fields including device ID, device type, grid-connected capacity, on-grid electricity price, monthly power generation, operation and maintenance costs, and others. Units include megawatts, yuan per kilowatt-hour, ten thousand yuan, and additional units as needed.
Constraints on Workflow Orchestration
Differences in update frequencies across multiple data sources require setting layered synchronization windows in workflows. This avoids yield calculation errors caused by mixing data from different cycles. Differences in multi-dimensional fields and units require configuring unified mapping rules. This ensures alignment of device identifiers and accounting parameters across different data sources. Device data association relies on unique identifiers. Workflows must include deduplication checks, to prevent duplicate pulled data for the same device from interfering with merge results. Inconsistent units across different fields require configuring unit conversion nodes. This ensures consistent measurement standards for all accounting parameters.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
data_fetch_interval | 1 minute (real-time operating data), 24 hours (daily revenue data) | Matches the update frequency of the corresponding data source, to avoid expired data or repeated pulls |
field_mapping | Device ID → Grid-connected Device Identifier | Unifies device identification fields across multiple data sources, eliminating identifier differences across sources |
unique_key | Device ID | Serves as the core identifier for data association and deduplication, ensuring duplicate merging of data for the same device does not occur |
unit_conversion | Unify units using official published electricity price conversion coefficients | Aligns accounting units for on-grid electricity prices and operation and maintenance costs, ensuring accurate yield calculations |
workflow_timeout_seconds | 600 seconds | Covers the full process duration of multi-source data pulling, field conversion, and result merging |
parallel_node_limit | 2 | Matches the parallel pulling scale of power grid equipment data, avoiding exceeding interface call limits of data sources |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis; it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Errors
- Symptom: Workflow runs with empty variable fields, failing to complete data association. Cause: Variable initialization rules are not configured correctly; core variables such as device ID are not set to globally visible, causing downstream nodes to fail to read required parameters.
- Symptom: Batch starting AI conversation nodes triggers a
429 Too Many Requestserror, with some nodes failing to execute. Cause: Parallel node count is not limited; too many simultaneous AI calls exceed interface quotas. - Symptom: Query and merge module output contains duplicate device entries, making accurate daily reports impossible to generate. Cause: Deduplication rules are not configured in the query and merge node, causing multiple pulled copies of data for the same device to be merged repeatedly.
How to Confirm Proper Configuration
- View the workflow's data source configuration panel, confirming the
data_fetch_intervalparameter matches the update frequency of the corresponding data source. - Run a single test workflow, checking if the output fields of the variable initialization node include all configured device identifiers and revenue fields.
- Review workflow logs, confirming the
unique_keyparameter is active and the merge result contains no duplicate device data. - Check the running status of parallel nodes, confirming the number of simultaneously running nodes does not exceed the configured
parallel_node_limitvalue.
