Abstract
An electric machine and sitewide control system and method that use a trolley power system at a worksite is disclosed. The trolley power system allows electric machines at the worksite to draw power from the trolley power system to concurrently operate to perform tasks and recharge their batteries. This allows the batteries on electric machines to be smaller than they would otherwise be, since a fully charged battery is not needed when operational power can be drawn from the trolley power system. The trolley power system is segmented, such that if one segment is faulted, the other segments can operate to provide power to electric machines at the worksite. Additionally, a sitewide controller initiates operational changes, such as a change in speed, for the electric machines at the worksite to compensate for one or more faulted segments.
