【摘要】 辅助服务主要是指在电力市场中为保障电力系统安全与电能质量合格,实现电能传输和交易的各种措施。是电力系统安全稳定运行的重要组成部分,是特殊的电力商品。在不同的电力市场中,由于电网结构、电源与负荷的分布特点、负荷特性等的不同,所需辅助服务的种类与数量也不同。核能是清洁、环保、经济的能源,核电是目前我国大力发展的电源形式之一,世界范围内很多其他国家也在积极的推行核电。一般来讲,出于安全性和经济性考虑,核电通常带基荷按恒定功率运行,基本不参与调峰、负荷跟踪等系统调节任务。近年来,随着电力需求的不断增加,系统峰谷差逐渐增大,系统调峰的难度逐渐增加,在此背景下,核电是否有必要、是否可以提供辅助服务已成为一个值得探讨和研究的问题,核电应如何参与辅助服务,逐渐成为大家比较关注的问题。本文将结合我国的实际情况,重点分析南方区域辅助服务现状,从技术、经济、政策等角度研究核电机组参与辅助服务的可行性与必要性,理顺核电机组与抽水蓄能电站的关系,解决核电参与辅助服务与支付抽水蓄能租赁费之间的衔接问题,对制定核电机组参与辅助服务的政策提出建设性的意见,以提高系统的运行水平,保证系统的安全性、稳定性和经济性。更多还原

【Abstract】 Ancillary services mainly refer to various measures to ensure the safety of electric power system and the eligibility of electric energy quality, and measures to realize electric power transmission and transaction. Aucillary services are special power commodities, they play an important part in safe and stable operation of electric power system. In different power markets, the type and number of required ancillary services vary as a result of differences of power grid structures, distribution characteristics of power source and load, load-frequency and load-voltage characteristics.Nuclear energy is a clean, environmental-friendly and economical energy source. At present, nuclear power plant is one of the power source which is vigorously developed by our country in special and by many other countries worldwide in general. Normally, for the reasons of safety and economy, nuclear power plant is operated with base load and constant power, and basically, it is not used for power system regulation, such as peak load regulation and load following. In recent years, with the electricity demand growing rapidly, the peak-valley difference has been increasing gradually, which makes power system regulation more difficult. In such case, whether it is necessary or possible to use nuclear power plant as ancillary service become a question which is worth investigating and studying, and how can nuclear power plant be a part of ancillary service also become a question which is attracting more attention.This article is written in the light of actual situation in our country to focus analysis on the current situation of ancillary services in the southern region, to study the feasibility and necessity of being a part of ancillary services for the nuclear power units province in terms of technology, economy and policy, to straighten out the relationship between nuclear power units and pumped storage hydropower plants, to solves the connecting problem between nuclear generators’participating in assistant service and paying pumped-storage rental fee, to give constructive opinions on how to work out the policy for using nuclear power units as ancillary services so as to improve operation standard and ensure the safety, stability and economy of electric power system.更多还原
