摘要： A system and method of controlling a TCSC disposed on a high voltage line of an electrical transmission network. The system comprises: (a) a voltage measuring module; (b) a current measuring module; (c) a regulator, working in accordance with a non-linear control law to receive on its input the output signals from the two modules for measuring voltage and current, and a reference voltage corresponding to the fundamental of the voltage which is to obtained across the TCSC; (d) a module for extracting the control angle in accordance with an extraction algorithm; and (e) a module for controlling the thyristors (T1, T2) of the TCSC, and for receiving a zero current reference delivered by a phase-locked loop which gives the position of the current.

摘要： An apparatus for controlling a thyristor controlled series capacitor connected to a power transmission line. A thyristor firing control includes a unit for effectuating a desired capacitor voltage zero crossing in dependence of a line current and a capacitor voltage in response to a command signal. A command control provides the command signal to the thyristor firing control. The command control includes a damping control including a damper configured to damp at a least one discrete frequency.

摘要： An overload management system is provided, including a method and an apparatus, for controlling the operation of electrical equipment in a short-term overload region above the equipment's continuous capability operation curve, without suffering significant loss of equipment life. This overload management system is particularly beneficial for use with equipment having load management capability, such as a modular thyristor controlled series capacitor (TCSC) system using phase controlled firing based on monitored capacitor voltage and line current. For vernier operation, the system predicts an upcoming firing angle for switching a switching device to govern the current received by the electrical device, such as to bypass line current around a series capacitor of the TCSC system. The overload management system may serve as one of several higher-level controllers providing input to a vernier controller for accommodating competing objectives of various system demands.
