By building a negative feedback and dynamic balanced management mechanism, ECPRCB （East China Power Regulation Center Branch） is able to keenly sense the internal and external changes, efficiently coordinate all kinds of resources and improve the operational performance. As a result, self-adaptive management effectively boosts ECPRCB to reach the goal of being a world-class dispatching center with high operational performance, competent internal operation, adequate resources support and strong growth motion.展开更多
