Abstract

The invention discloses a redundancy architecture method of plant-level AGC (Automatic Generation Control) access to a power monitoring network. The redundancy architecture method of the plant-level AGC access to the power monitoring network comprises the following steps of 1) adding a plant-level AGC load optimization control device at a process control level of a power plant supervisory information system and adopting redundancy configuration; 2) establishing communication between the plant-level AGC load optimization control device and a background as well as a RTU; and 3) establishing communication between the plant-level AGC load optimization control device and a machine set information acquisition system. On the basis of not affecting an existing power network topological structure, the plant-level AGC load optimization control device is added, a complete systemic redundancy strategy is formulated, and the redundancy performance of the real sense is realized.

Description

technical field [0001] The invention relates to a redundant framework method for connecting a plant-level AGC to a power monitoring network, and belongs to the field of plant-level load dispatching in thermal power plants. Background technique [0002] With the continuous increase of the unit capacity of the power plant, the automation level of the unit is also higher and higher. The plant-level AGC has gradually changed the previous single-unit automatic generation control (stand-alone AGC) method that directly sends load instructions to the generator set in the power grid. After receiving the plant-wide load command or planning curve issued by the dispatcher, according to the principle of "unified dispatching and hierarchical management" and the ordering requirements of energy-saving power generation dispatching, according to the detailed performance parameters of each unit, automatically and reasonably optimize the combination of the plant-wide units and load distribution...
