GB/T 36045-2018Supervision specification of unit capacity expansion retrofit for coal-fired power plants (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

Introduction

In recent years, the capacity expansion of coal-fired thermal power units has generally been carried out throughout the country. There are two main motives for power generation companies to implement capacity expansion.

First, under the planned system, increasing the capacity of the unit can be used to obtain more power generation plan targets, so as to obtain additional benefits;

Capacity transformation, increase power generation output, reduce coal consumption and improve economic efficiency. The motivation is different, and the operation method and the final effect of implementing the capacity expansion reform are not with. Due to the lack of a unified regulatory standard, the increase in capacity of units has emerged in operational procedures, technical indicators, safe operation, and practical results.

Problems, such as capacity expansion of some units can only be operated in a short period of time under certain operating conditions, poor economic performance, large life loss, primary frequency modulation capability and phase-in operation The capacity has dropped significantly. In order to ensure the orderly expansion of the scientific and normative regulations for increasing capacity and to ensure the safe and economical operation of the power system, the Based on the relevant technical standards of the electric power industry and the laws and regulations of electric power supervision, the regulatory standards for the expansion of coal-fired thermal power units have been formulated.

1 Scope

This standard stipulates the applicable scope, modification conditions, capacity test and performance requirements and capacity of the capacity-increasing transformation of coal-fired thermal power units. Appraisal of regulatory technical indicators and methods in such areas.

This standard applies to the regulation of the expansion of coal-fired thermal power units.
