Genset Remote Start Control Mode Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of generator sets (gensets) face the challenge of not being able to remotely stop or restart them during extended power outages, requiring physical presence to conserve fuel and reduce noise when backup power is not needed.
Innovation Solution
A system and method for controlling gensets that includes local and remote interfaces, allowing users to select modes such as remote start, remote stop, and remote standby, enabling remote activation and deactivation of the genset based on conditions or user commands, while disabling local standby mode when remote modes are active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the genset is enabled in Auto Enabled or Standby mode for remote starting, then the genset can be automatically activated by a command from an automatic transfer switch during power outages, but the user cannot remotely stop or restart the genset during extended power outages to conserve fuel or reduce noise
Solution Approach 1:
The control system is segmented into multiple independent mode options (local start, local stop, remote start, remote stop, standby mode) that can be individually selected and combined. This segmentation allows the user to enable only the specific remote control functions needed while maintaining other operational modes, thereby improving ease of remote operation without sacrificing overall system adaptability.
Solution Approach 2:
The system dynamically adjusts its operational characteristics based on the selected mode. When remote start or remote stop modes are enabled, the genset becomes responsive to remote commands for those specific functions while maintaining local control capabilities. This dynamic configuration allows the system to adapt to different operational scenarios, resolving the contradiction between ease of remote operation and overall system versatility.
2Adaptability or versatility
If multiple modes are available for genset control, then the system is versatile and adaptable to different scenarios, but the control system becomes complex with multiple modes to manage
Solution Approach 1:
The control system implements a universal interface that handles multiple mode selections through a single integrated controller. Rather than requiring separate control systems for each mode (local start, local stop, remote start, remote stop, standby), one multi-functional controller manages all modes, reducing overall system complexity while maintaining full versatility.
Solution Approach 2:
The system manages complexity by changing operational parameters (mode selections) rather than requiring structural changes. Each mode represents a different parameter configuration of the same control system, allowing versatile operation without proportionally increasing physical or structural complexity.
3Reliability
If the genset runs continuously during power outages to ensure backup power availability, then reliability is improved, but fuel consumption increases and noise is generated when backup power is not needed
Solution Approach 1:
The remote stop capability provides feedback control to the genset operation. Users can monitor the need for backup power and provide feedback by remotely stopping the genset when backup power is not required, allowing the system to adjust its operation based on actual demand rather than running continuously, thereby reducing fuel consumption while maintaining reliability when needed.
Solution Approach 2:
Instead of continuous operation, the genset can be periodically activated and deactivated based on remote commands. This periodic action allows the system to provide backup power only when necessary, reducing overall fuel consumption and noise while maintaining reliability during actual power outage events.

AI summary
Systems and methods for controlling a generator set are disclosed herein. The method includes determining a state of local modes selectable via a local interface proximate to the generator set. The local modes include a local standby mode and a local remote enabled mode. The method also includes determining a state of a plurality of remote modes using a command from a device remote from the location of the generator set in response to determining the remote enabled mode is active. The method includes, in response to determining the local standby mode is active, the remote enabled mode is active, and one of the remote modes is active, determining whether to activate or stop the generator set based on the active remote mode and disabling the local standby mode from controlling activation of the generator set.
