Introduction

GB/T 36045—2018 Interpretation of the Regulatory Specifications for Capacity Expansion and Reconstruction of Coal-fired Thermal Power Units

Background of Standard Formulation and Analysis of Technology Evolution

In recent years, capacity expansion and reconstruction of coal-fired thermal power units has become an important means to improve power generation efficiency and economic benefits. However, due to the lack of unified technical standards and regulatory specifications, some units have encountered problems such as inaccurate capacity verification and decreased performance indicators during the reconstruction process, which has seriously affected the safe and stable operation of the power system.

Scope of application and core requirements

Renovation conditions Technical indicators Performance requirements
Single unit capacity: Pure condensing units should not be less than 200MW, and heating units should not be less than 100MW Renovation age requirements: The commissioning time should be more than 5 years, and the operation should be stable Power supply coal consumption: Not higher than the power supply coal consumption before renovation
Main equipment calibration: The manufacturer needs to perform calibration and calculation according to the capacity after capacity increase Operation stability: Meet the safety and stability requirements of the power system Environmental emissions: Comply with national and local environmental standards

Performance testing and verification after capacity expansion and reconstruction

According to relevant standards such as DL/T1166 and GB/T30370, coal-fired thermal power units are required to undergo a number of performance tests after capacity expansion and reconstruction:

  • Primary frequency regulation test: Ensure that the frequency regulation capability is not less than 3%Pe
  • Leading phase operation capability: The generator has the operating capability of lagging phase 0.90 and leading phase 0.95
  • AGC performance test: Meet the grid's requirements for regulation response speed and accuracy

Implementation recommendations and compliance points

To ensure the scientificity and standardization of the capacity expansion and transformation of coal-fired thermal power units, it is recommended that power generation companies pay attention to the following points during the implementation process:

  1. Preliminary evaluation: Comprehensively evaluate the technical, economic and safety of the unit to avoid blind transformation
  2. Technology selection: Select advanced technologies and equipment that meet the capacity expansion requirements to ensure performance improvement after the transformation
  3. Compliance declaration: Submit capacity change applications to relevant competent authorities in strict accordance with standard requirements and provide true and accurate technical information
  4. Continuous supervision: After the transformation is completed, regularly monitor the operating status of the unit to ensure that all indicators meet expectations

Conclusion

The implementation of GB/T 36045-2018 provides clear technical guidance and regulatory framework for the capacity expansion and transformation of coal-fired thermal power units, which is conducive to improving the overall technical level and operational efficiency of my country's power industry. Power generation companies should strictly follow the standard requirements in actual operations to ensure that the transformation work is completed in compliance and efficiently.
