Embodiment Construction

[0029] The specific implementation of the technical solution of the content of the invention will be further described in detail below. Such as figure 1Shown is a schematic diagram of the data structure of the electric thermal engineering integrated control system of the power plant of the present invention. In the integrated control system of electrical and thermal engineering in power plants, there are mainly three types of controllers (ie control units): thermal engineering control DPU, electrical control DPU, and fieldbus communication module CA. Various types of IO modules and self-defined IED devices are configured under the thermal controller DPU to complete the data acquisition and control functions of the thermal control part of the integrated electrical and thermal control system of the power plant. The IO modules mainly include the analog quantity acquisition module AI , analog output module AO, digital acquisition module DI, digital output module DO, pulse acquisi...

Abstract

The invention discloses a data processing method for an electrical and thermal integrated control system for a power plant. The method comprises the step of performing integrated data processing on a thermal controller digital processing unit (DPU), an electrical controller DPU and a field bus communication module CA. The thermal controller DPU, the electrical controller DPU and the field bus communication module CA in the power plant integrated control system are effectively combined to the same system platform, the data structure is clear, the database is perfect, the data comprises the thermal control part, the electric control part, the booster station control part and other whole-plant data information, and a foundation is laid for realizing electrical-thermal integrated control for the power plant.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a unified data processing method for an integrated control system of electrical and thermal engineering in a power plant. Background technique [0002] With the implementation of the national energy policy, energy saving, consumption reduction and operation and maintenance cost reduction are the essential requirements for thermal power plants to improve operating efficiency. The "Implementation Rules for Grid-connected Operation Management of Power Plants" began to vigorously assess and compensate the reliability and dispatchability of grid-connected generating units. These measures make it necessary for thermal power plants to continuously strengthen the efficiency, operational safety and reliability of generating units. [0003] At present, in most power plants in China, various monitoring systems are independent, such as thermal control system, auxil...
