摘要
当前,我国新能源等战略性新兴产业正迅猛发展,新能源发电不稳定的问题日益凸显。国家发改委、国家能源局正式发布《关于建立煤电容量电价机制的通知》(以下简称《通知》),明确自2024年1月1日起,我国建立煤电容量电价机制。该机制的实施将有力推动煤电转变经营发展模式,促进我国新能源加快发展和能源体系绿色低碳转型。煤电作为我国最重要、成本较低的支撑调节电源,推动煤电加快向提供容量支撑保障和电量并重转型,对促进新能源进一步加快发展具有重要意义。随着电网对煤电机组的可靠性要求越来越高,煤电机组参与深调,频繁启动及大幅负荷变动,机组需承受大幅度的温度和应力变化,关键零部件疲劳损伤风险明显加剧。国家重大科技基础设施“重大工程材料服役安全研究评价设施”针对我国能源、交通及基础设施建设发展中关键材料和部件服役评价难题,建成多套具有国际领先水平的多环境因素耦合工况模拟大型科学试验装置,打破传统小试样单一环境的研究范式,为我国煤电机组应对新挑战提供了科学系统的解决方案。分析了煤电机组当前面临的技术瓶颈,结合该大科学设施服务能源装备案例,给出了新变化下发挥大科学设施作用,提升复杂工况下煤电机组可靠性的对策建议。
Currently,strategic emerging industries such as new energy in China are developing rapidly,and the problem of unstable new energy power generation is becoming increasingly prominent.Recently,the National Development and Reform Commission and the National Energy Administration officially issued the“Notice on Establishing a Coal Electricity Capacity Pricing Mechanism”(hereinafter referred to as the“Notice”),which specifies that China will establish a coal electricity capacity pricing mechanism from January 1,2024.The implementation of this mechanism will effectively promote the transformation of coal-fired power generation’s business development model,accelerate the development of new energy in China,and promote the green and low-carbon transformation of the energy system.As the most important and low-cost supporting and regulating power source in China,coal-fired power is of great significance in promoting the transformation of coal-fired power towards providing capacity support and balancing electricity consumption,and further accelerating the development of new energy.With the increasing reliability requirements of the power grid for coal-fired power units,they participate in deep regulation,frequent start-up,and significant load changes.The units need to withstand significant temperature and stress changes,and the risk of fatigue damage to key components is significantly increased.The National Major Science and Technology Infrastructure“Major Engineering Material Service Safety Research and Evaluation Facility”aims to address the challenges of service evaluation of key materials and components in China’s energy,transportation,and infrastructure construction and development.Multiple sets of internationally leading multi environmental factor coupled working condition simulation large-scale scientific testing devices have been built,breaking the traditional research paradigm of small samples and single environments,this provides a scientific and systematic solution for China’s coal-fired power units to cope with new challenges.This article analyzes the current technological bottlenecks faced by coal-fired power units,and based on the case of the large scientific facility serving energy equipment,provides countermeasures and suggestions for leveraging the role of large scientific facilities under new changes and improving the reliability of coal-fired power units under complex working conditions.
