The Group level gives the practitioner a closer look at what the culture is, how communication flows, and how well each component is aligned with the overarching design of the organization. The outputs examined in this case are team effectiveness, quality of work life, and performance.

Low voltage microgrid group independent coordination control system

Provided is a low voltage microgrid group independent coordination control system, employing a layered control structure, i.e., an equipment layer, a grid control layer and a group control layer. A microgrid group controller receives a scheduling instruction of a group level energy management system; based on the safety and reliability of a control target of the microgrid group and sub microgrids, the microgrid group controller controls exchanging power between a microgrid group and a power distribution network and each sub microgrid, grid disconnection or grid connection of the microgrid group, and grid connection or grid disconnection of the sub microgrids, realizes interface control between the sub microgrids and the microgrid group, and meanwhile issues a control instruction to a grid level controller. The grid level controller works out optimal control strategies of distributed power supply, energy storage and load, and realizes stable operation and smooth transition among states of the sub microgrids in a grid connection state, and information communication with the microgrid group controller. A supply or energy storage local controller completes primary regulation of frequency and voltage of distributed power supply and energy storage; a load controller completes load grading control.

System structure of power generation group-level hydro-power generating unit distributed state monitoring and diagnosis platform construction

The invention relates to a system structure of power generation group-level hydro-power generating unit distributed state monitoring and diagnosis platform construction. The system structure includes an overall technical architecture, a business architecture, an information/data architecture, an application architecture, a technical architecture, infrastructure and the like. According to a platform, based on unified codes, three levels of data centers are established to realize distributed data acquisition, storage and application; data are divided, pushed and extracted according to data characteristics and application requirements, so that network communication pressure and data maintenance quantity can be can effectively reduced, and therefore, the real-time performance of the data can be enhanced; application modules of the platform provide an application market which can provide application services for 9 levels of user roles according to needs; and mutual communication and sharing of information such as monitoring data, control dispatching, diagnosis results and policy-making instructions between a monitoring and control system, a regional centralized control analysis and diagnosis system and a group monitoring and diagnosis system of a station can be realized, and solutions can be provided for the power generation group-level hydro-power generating unit distributed state monitoring and diagnosis platform construction.
