HTTP Interfaces and External Systems for Grid Equipment

What the data for this category looks like

Data for grid equipment intelligent due diligence reports comes primarily from grid SCADA monitoring systems, online condition monitoring devices including infrared temperature sensors and partial discharge sensors, equipment operation and maintenance logs, and publicly available grid industry operation and maintenance databases.

Data update frequency falls into three categories:

Real-time monitoring parameters such as bus voltage and line current update once per second.
Operation and maintenance logs and defect records update daily.
Batch inspection data updates weekly.

Document structures include fields such as unique device identifier, model specifications, operating parameters including voltage, current, temperature, and others, defect level, operation history, and installation location. Voltage is measured in kV, current in A, and temperature in ℃. Defect levels use standardized numeric coding.

What constraints these characteristics impose on HTTP interfaces and external systems

Highly time-sensitive monitoring parameters require interfaces to support high-frequency short connection calls, to avoid excessive latency and data loss. Multi-source data access requirements mean interfaces must support request and response structures in different formats, and allow custom field mapping. Strict unit and field specifications require interface returned data to fully match preset formats. Non-compliant data cannot be included in due diligence reports. Large data volumes and frequent updates require interfaces to support incremental data pulling and batch request limits, to avoid overloading external systems. Grid data compliance rules mandate that interfaces use HTTPS encrypted transmission, and require a dedicated authentication mechanism.

Configuration Settings

Configuration Item	Recommended Setting	Rationale
`WEBHOOK_SIGN_SECRET`	32-character random string	Ensures HTTP interface authentication security, prevents unauthorized request access
`API_REQUEST_TIMEOUT`	`30 seconds`	Grid equipment data includes multiple sets of monitoring parameters. An overly short timeout will cause loss of complete data
`SYNC_INCREMENTAL_SWITCH`	Enabled	Grid equipment data volume is large. Incremental synchronization reduces interface call frequency and external system load
`FIELD_UNIT_VALIDATION`	Enabled	Grid equipment parameters have strict unit specifications. Automatic validation filters abnormally formatted data
`BATCH_REQUEST_LIMIT`	First 100 entries	Too many single batch requests exceed external system processing capacity. Limiting the number of entries ensures request stability

The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. Testing against local samples prior to final configuration is recommended.

Three Common Misconfigurations

Symptom: External interface returns 401 Unauthorized status code. Cause: The WEBHOOK_SIGN_SECRET parameter is not configured correctly, resulting in interface authentication failure.
Symptom: OneAPI-related configuration items cannot be found in the docker compose deployment environment. Cause: Environment variable entries for ONEAPI_BASE_URL and ONEAPI_API_KEY are not added to the deployment configuration file. Some versions do not include a visual entry for this configuration by default.
Symptom: Tabular data received via webhook does not match expected fields. Cause: The FIELD_UNIT_VALIDATION configuration is not enabled, and no validation is performed on the unit and field format of returned data, resulting in abnormal data being ingested.

How to Confirm Successful Configuration

Call the configured HTTP interface, check if the response header includes the configured authentication signature field to confirm that the authentication configuration is active.
Send a single test request to verify that returned data fields and units comply with grid equipment data specifications, confirming that the field validation configuration is active.
Review external system request logs to confirm the presence of legitimate requests from the configured interface, confirming that synchronization cycle and batch request limit configurations are active.
Check the docker compose environment variable list to confirm that ONEAPI_BASE_URL and ONEAPI_API_KEY are correctly configured, confirming that third-party service connection configurations are active.
