DCS性能评价标准在华东电网应用探讨

Discussion on Application of Disturbance Control Standard in East China Power Grid

简要介绍了北美电力可靠性协会(NERC)的扰动控制标准(DCS),通过对DCS技术特点的分析,阐明了DCS与控制区区域控制偏差(ACE)、电网频率以及控制性能标准(CPS)之间的影响。结合华东电网典型扰动事故分析,认为DCS指标可以有效地反映控制区事故备用能力。针对华东电网各省市能量管理系统(EMS)的特点,提出了在华东电网实施DCS的技术可行性,指出实施DCS标准为华东电网合理配置备用容量提供了技术评价手段,并节约了系统资源。最后结合DCS性能监视要求,提出了对网、省(市)自动发电控制(AGC)软件进行相应调整的思路。

The disturbance control standard （DCS） commended by North American Electric Reliability Council （NERC） is briefly introduced. By analyzing the technical characteristics of DCS, the relationship between DCS and area control error （ACE）, system frequency and control performance standard is described. To combine the disturbance accident happened in East China power grid （ECPG）, it is pointed out that the ability of accident reserve of control areas in ECPG can be effectively reflected. Aimed at the characteristic of energy management system （EMS） in ECPG, the feasibility to implement the DCS in ECPG is put forward to provide technical evaluation means for reasonably deploying the reserve capability and save the system resources. By combining the monitoring demand of DCS, the adjusting guidance for the automatic generation control （AGC） system in the control areas of ECPG is proposed.
