Abstract:

In order to achieve the economic distribution of load among different units in plant, Guangdong Honghaiwan Generation Company Limited launch a set of external plant level automatic generation control (AGC) system. AGC command turns from the original load command for single unit to load command for the whole plant. After acceptance of load command for the whole plant, load optimization calculation is made by plant level AGC server.  It introduces the construction of plant level AGC system, structure and process of software at plant level, and summarizes the key designing points of AGC system. After the operation of the system, accuracy of every channel, the load command distribution, load change rate and response to primary frequency modulation can satisfy the requirements of grid. The load distribution right of each unit is obtained by the plant side.

Key words:

plant level automatic generation control system, optimization, load distribution
