摘要： Converter stations (104) have real and reactive power set points initially determined as part of a main loadflow analysis routinely performed on the AC power system connected to the converter stations (104). Viable real and/or reactive power set points for the converter stations (104) can be identified by calculating real and/or reactive power set point candidates for the converter stations (104) before the main loadflow analysis is performed again on the AC power system. The power set point candidates are calculated based on information determined as part of a previous iteration of the main loadflow analysis on the AC power system. The power set point candidates which violate an operating constraint imposed on the AC power system are identified, and a region of valid power set points is defined for the converter stations (104) that excludes the power set point candidates which violate an operating constraint imposed on the AC power system.

摘要： The present invention is concerned with a distribution controller (19) for controlling a distribution of electrical power in an assigned first power distribution region (1). The controller is adapted to be connected to process devices (21) which in turn interact with primary devices (5, 7, 9, 11, 13) of the assigned first region. The distribution controller is provided with a standardized, machine-readable network description of the first region and comprises means to identify, following a network reconfiguration, the extent of an orphan network section (23) that is no longer connected to the first region. The distribution controller is further adapted to transmit a description of the orphan network section to a second distribution controller (19') controlling a second or neighbouring power distribution region (1') to which the orphan section has been connected as a consequence of the network reconfiguration. Due to this capability of transmitting descriptions of the network section changing hands, there is no need to keep and update a description of the entire network in each controller of the power distribution system.

摘要： The present invention is concerned with an improved time synchronisation of two stationary clocks. A global time signal from a global time reference or common time source is used to calculate a common view based clock offset between two stationary clocks. In parallel, a network based clock offset between the two clocks is calculated based on messages exchanged over a communication network interconnecting the two clocks and without reverting to the global time reference. The two most recent values of the common view and network based clock offsets are then combined or superposed in a seamless or hitless way to produce a final time offset estimate. The combination of the independently calculated common view and network based clock offsets is a weighted average of the two values, involving respective weights based on quality estimates of the latter. Preferably, the time synchronization schemes based on the Global Positioning System (GPS) and a wide area communication network are combined in order to synchronize the stationary clocks of the Phasor Measurement Units (PMUs) of a Wide Area Monitoring System to a central server clock at the Network Control Center (NCC) of the system.
摘要翻译：本发明涉及两个固定时钟的改进的时间同步。来自全局时间参考或公共时间源的全局时间信号用于计算两个固定时钟之间的基于公共视图的时钟偏移。并行地，基于通过互连两个时钟的通信网络交换的消息来计算两个时钟之间的基于网络的时钟偏移，并且没有恢复到全局时间基准。然后将共同视图和基于网络的时钟偏移的两个最新值以无缝或无限制的方式组合或重叠以产生最终时间偏移估计。独立计算的共同视图和基于网络的时钟偏移的组合是两个值的加权平均值，涉及基于后者的质量估计的相应权重。优选地，组合基于全球定位系统（GPS）和广域通信网络的时间同步方案，以便将广域监控系统的相量测量单元（PMU）的固定时钟与中央服务器时钟同步系统的网络控制中心（NCC）。

摘要： Phasor measurement units (108) provide phasor data from various locations (102) in an electrical power system. The phasor data is referenced to a common timing signal. Non-phasor measurement data is also obtained at various locations in the power system. A phasor assisted state estimator (120) uses the phasor data and the non-phasor data to determine the power system state.

摘要： The present invention is concerned with a limitation of the interaction between cascaded tap changers and/or between a tap changer and a shunt compensator independently of any real-time communication between the respective controllers. According to the invention, coordinated voltage control in distribution networks is enabled by an adaptive updat ing or tuning of control parameters DB4, TD4 of a voltage control unit (41) controlling a second voltage control device (40), depending on instantaneous or actual operating conditions evaluated by the voltage control unit itself. Instead of using constant control parameters initially set by a commissioning engineer, the former are updated based on a voltage level U P 4 , which in turn is responsive to or affected by any control action performed by a first voltage control device neighbouring the second voltage control device. The voltage control unit calculates a deviation of an instantaneous value of said voltage level from a reference value, and translates or maps this deviation to an update of it s dead bands and/or time delay characteristics. Hence, the voltage control unit inherently anticipates, or determines a likelihood of, a control action of the first voltage control device, without the need for a real-time transmission of this piece of information to the voltage control unit.
