摘要

介绍了一种自耦变压器与系统能量控制中心之间闭环的自动LTC控制系统的实现。该方案利用能源管理系统计算机上的最优潮流(OPF)计算输入，通过安装在变压器上的调压继电器的监控和数据采集(SCADA)来偏置中带设定值。有关变压器系统参数的数据随后通过SCADA发送回能源管理系统计算机，以便进一步改进以获得最佳潮流。这种控制行为的净效果是使输电网电压水平变平，并重新平衡无功流，以满足负载条件和可用的无功源。

Optimal real-time voltage control with an advanced LTC control system

The implementation of an automatic LTC control system that closes the loop between the autotransformer and the system energy control center is presented. The scheme uses the input of an optimal power flow (OPF) calculation on the energy management system computer to bias the centerband setpoint via a supervisory control and data acquisition (SCADA) of the voltage regulating relay installed on the transformers. Data regarding system parameters at the transformer are then sent back through SCADA to the energy management system computer for any further refinements for optimum power flow. The net effect of this control action is to flatten the transmission network voltage levels and rebalance the reactive flows to meet the load conditions and available reactive sources.<>
