Abstract: Unique systems, methods, techniques and apparatuses of a distribution system are disclosed. One exemplary embodiment is an alternating current (AC) distribution system including a first substation including a first transformer and a protective device; a first distribution network portion coupled to the first transformer; a second substation; a second distribution network portion; a DC interconnection system coupled between the first distribution network portion and the second distribution network portion; and a control system. The control system is structured to detect a fault in the first transformer or the transmission network, isolate the first distribution network from the fault, determine a set point of the DC interconnection system, and operate the DC interconnection system using the set point so as to transfer a portion of the MV AC from the second distribution network portion to the first distribution network portion.

Abstract: The present disclosure relates generally to medium voltage alternating current (MV AC) distribution networks. Isolating a fault in a feeder line of an MV AC distribution network may cause a healthy portion of a feeder line to be disconnected from all power sources. Network control systems may be able to reconnect the healthy portion to another feeder line using controllable switches such as tie switching devices coupled to the end of each feeder line. Existing MV AC distribution networks suffer from a number of shortcomings and disadvantages. There remain unmet needs including increasing reconfigurability following feeder line fault response, preventing subsequent overloads after network reconfigurations, and reducing network downtime for healthy feeder line portions. For instance, conventional distribution networks do not receive power from multiple connected feeder lines after a fault response, risking an overload in a single newly connected feeder line and reducing power transfer ability. In view of these and other shortcomings in the art, there is a significant need for the unique apparatuses, methods, systems and techniques disclosed herein.

Abstract: The present disclosure relates generally to power collection systems. In some power collection systems, such as a power collection system for a large solar panel array, the voltage of the collected power must be increased to medium voltage levels to allow for efficient power transmission from the solar panel array to the utility grid. In some power collection systems, medium voltage direct current (MVDC) power transmission is more efficient to collect power compared to medium voltage alternating current power transmission. Existing power collection systems suffer from a number of shortcomings and disadvantages. There remain unmet needs including decreased protection system response time, decreased system downtime, and increased system flexibility. For instance, circuit breaker and relay based protection schemes may not adequately protect collection system components in MVDC collection systems where fault currents increase rapidly. Furthermore, in some power collection systems, a single fault may shut down an entire power collection system until it can be repaired by a technician. There is a significant need for the unique apparatuses, methods, systems and techniques disclosed herein.

Abstract: While transient current magnitudes at different locations within a DC distribution system themselves are not a reliable indicator of fault location, it is recognized herein that accumulating energy or pseudo energy values provides a reliable basis for tripping the protection element at a fault location. Thus, in one aspect of the teachings herein, pseudo energy values are accumulated independently during a fault condition, for each of one or more protected branch circuits and the protection element for each such branch circuit is tripped responsive to the accumulated pseudo energy values reaching a defined pseudo energy threshold. The pseudo energy thresholds are defined so that the protection element in the branch circuit where the fault is located will trip first.
Abstract translation: 虽然在DC分配系统本身内的不同位置处的瞬态电流幅度不是故障定位的可靠指标，但是这里可以认识到，累积能量或伪能量值为故障位置处的保护元件跳闸提供了可靠的依据。 因此，在这里的教导的一个方面，对于一个或多个受保护的分支电路中的每一个，在故障状态期间独立地累加伪能量值，并且每个这样的分支电路的保护元件响应于累积的伪能量值达到 定义的伪能量阈值。 定义伪能量阈值，使得故障所在的分支电路中的保护元件首先跳闸。
