The stand-by feedwater pump should be put in service as soon as the operating pump is tripped out.

在高温、高压运行的环境下,给水泵出现机械故障的概率很大,因而要求当运行给水泵出现故障,备用给水泵能及时快速地响应,因此需具备一套完善的联锁保护设计方案。

Discussion of load resource in reserve market;

负荷参与备用市场的讨论

Compensation fees for AGC is based on availability、regulating capacity,regulating speed,regulating precision and the response time,peak adjustment is based on losing energy and times of start-stop;reserve is based on reserve capacity and duration;reactive power and voltage support is based on the influence to active power;black start-up restore is based on the requirements .

从实用化出发,提出了我国现阶段电力市场辅助服务补偿机制的设计原则,并建立了AGC依据可用率、调节容量、调节速率、调节精度和响应时间、有偿调峰依据深度调峰损失电量及启停调峰次数、备用依据备用容量和备用时间、有偿无功调节依据无功调节对有功电量的影响、黑启动依据电网系统安全可靠要求来计算贡献量进行补偿的数学模型,特别针对我国调节性能优良的水电建立了有偿调峰弃水电量、无功调节损失电量的补偿机制数学模型。

In the traditional vertically integrated utility, the generators always provide reserve without any payment.

在计划管理体制下,发电企业所提供的备用服务是无偿的;在较完善的电力市场机制下,则要通过科学、合理的备用服务定价来调动发电企业提供备用服务的积极性。

Utilizing the powerful functions and flexibility of the Harris 2020 switching system and the ADV digital dispatching system, we have realized the simulation training and standby function of dispatching system through extending hardware and flexibly applying software system.

利用H20 20交换机和ADV数字调度系统功能强大、应用灵活的特点,通过对现有系统硬件的扩充和软件的灵活应用,实现调度系统的仿真培训和备用功能。

As one of the most important ancillary services, power reserves play a very important role in maintaining power system security and reliability.

备用辅助服务是电力系统的重要特征之一 ,关系到电力系统的安全运行与可靠性。
