Abstract: A method for controlling a genset system is provided. The method includes recognizing a communication failure between one or more gensets of a plurality of gensets and a control system and determining an operating state of each of the one or more gensets prior to the communication failure. The method further includes operating the genset system, upon communication failure, according to a load control scheme. The load control scheme includes determining an available power of the genset system based on the determined operating state of each of the one or more gensets and coupling one or more loads to the genset system based on the available power.

Abstract: A method of controlling a plurality of gensets during a failsafe condition is provided. The method may include operating one or more of the gensets according to a modified isochronous control scheme, and operating a remainder of the gensets according an adaptive droop control scheme. The modified isochronous control scheme may include varying the frequency of each isochronous genset with respect to load for lower-range loads and upper-range loads, and maintaining the frequency of each isochronous genset at nominal frequencies for mid-range loads. The adaptive droop control scheme may include adjusting the frequency of each droop genset to match the frequency of the isochronous gensets, and varying the load of each droop genset with respect to frequency for lower-range loads and upper-range loads.
Abstract translation: 提供了一种在故障安全状态期间控制多个发电机组的方法。 该方法可以包括根据修改的同步控制方案来操作发电机组中的一个或多个，并且根据自适应下垂控制方案操作发电机组的其余部分。 修改的等时控制方案可以包括相对于较低范围负载和较高范围负载的负载改变每个同步发电机组的频率，并且将中间范围负载的每个同步发电机组的频率保持在额定频率。 自适应下垂控制方案可以包括调整每个下垂发电机组的频率以匹配同步发电机组的频率，并且相对于较低范围负载和较高范围负载的频率改变每个下垂发电机组的负载。
