What the data for this category looks like
Power industry research report data mainly comes from publicly disclosed operational data of State Grid and China Southern Power Grid, annual and semi-annual reports of listed power companies, monthly operational briefings from industry associations, and special policy documents. Regular reports are updated monthly and quarterly. Special policy interpretations are updated immediately upon policy release. Each document includes four fixed modules: core data tables, supply and demand analysis, policy interpretation, and risk reminders. Core fields include installed capacity (unit: ten thousand kilowatts), power generation (unit: ten thousand kilowatt-hours), on-grid electricity price (unit: yuan/megawatt-hour). Metadata such as report issuing institution, release date, and report number are also included.
What constraints these characteristics impose on multi-turn dialogue and prompting
Data sources are scattered and update rhythms vary greatly. Multi-turn dialogue must clearly distinguish historical operational data from real-time policy information. Prompts must mandate specifying the corresponding time interval for data to avoid mixing up power operation indicators of different periods. Each document has a long length and fixed modules. The context window for multi-turn dialogue must be limited to core data and corresponding analysis modules to avoid interference from redundant information. Core fields have specific units. Prompts must explicitly require unified unit conversion to prevent mixing up ten thousand kilowatts and kilowatt-hours, yuan/kilowatt-hour and yuan/megawatt-hour. Special policies are updated in real time. Real-time data recall trigger logic must be configured to ensure returned content aligns with the latest policies.
How to set the configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
maxContext | 8000-12000 characters | Core modules of a single power industry research report are approximately 3000 characters. Retaining 3-4 rounds of context for multi-turn dialogue covers requirements and prevents window overflow |
recall_top_k | Top 6-8 entries | Power industry research report data fields are concentrated. Excessive recall will introduce non-core industry analysis content and affect accuracy |
CHAT_FILE_EXPIRE_TIME | 7 days | Regular power industry research reports are updated monthly. The expiration time matches the regular report cycle, and can be adjusted for special policy reports |
recall_similarity_threshold | 0.75-0.85 | Power industry data has high professionalism. A higher similarity threshold is required to filter irrelevant general industry content |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Power industry research reports often contain large data tables. Parsing takes longer than general documents |
max_tokens_per_call | 8000-10000 | Long text parsing and answer generation for power industry research reports require sufficient token space to avoid truncating core data |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. Testing on appropriate samples is recommended before finalizing.
Three Common Mistakes
- Phenomenon: An error message indicating that the token limit for a single AI dialogue call is exceeded. Cause: The
max_tokens_per_callparameter is not configured, or the value is set too small, failing to accommodate the token space required for long text data of power industry research reports and answer generation. - Phenomenon: The power industry research report files associated with the dialogue cannot be loaded, showing file not found. Cause: The value set for
CHAT_FILE_EXPIRE_TIMEexceeds the platform limit, or the expiration time is not adjusted to match the research report update cycle, causing the system to clean up the files early. - Phenomenon: Mixed units of power data returned in multi-turn dialogue, with simultaneous use of ten thousand kilowatts and kilowatt-hours, yuan/kilowatt-hour and yuan/megawatt-hour. Cause: The system prompt does not explicitly require unified unit conversion, and the context is not limited to only the core data fields required for the current round.
How to Confirm Correct Configuration
- Upload a power industry research report document, trigger a single-round question and answer, and check whether the returned content includes the core power data fields in the document.
- Initiate two consecutive related questions, check whether the context is correctly retained, and whether the answer follows the logic of the previous round of questions.
- Check the expiration time setting of the dialogue file, confirm that the value matches the update cycle of the power industry research report.
- Test the recall effect of different similarity thresholds, adjust until the professional matching degree between the returned content and the question meets the requirements.
