Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for any limitation of the present invention.

[0019] Example. The present invention is an improvement to the existing plant-level load distribution system of thermal power plants. At present, the load distribution of domestic thermal power plants adopts the direct adjustment method of automatic power generation control system, such as figure 2 shown. The power grid scheduling automatic energy management system EMS in the automatic power generation control system directly issues load instructions to the distributed control system DCS of each unit through the telecontrol terminal RTU according to the customer's load demand. In the current load distribution method, in many cases, the grid dispatching automatic energy management system EMS cannot know the equipment operation status of a specific unit. When an emergen...

Abstract

The invention discloses a method and a device for optimally allocating plant-level load for a heat power plant. The method comprises that: a load optimal allocation device is arranged between an automatical energy management system for electric network management and a group of distributed control systems of a machine set; the load optimal allocation device automatically configures a load optimal allocation proposal according to a command of the automatical energy management system for the electric network management and the load capability and machine set performance of the machine sets; and the automatical increase and decrease of the machine set loads are realized by the group of the distributed control systems of the machine set. The device is provided with the load optimal allocation device (LDS) which is arranged between a remote terminal unit (RTU) and the distributed control system (DCS) of the machine set; and the load optimal allocation device (LDS) is respectively in double-way connection with the remote terminal unit (RTU) and the distributed control system (DCS) of the machine set. In the premise of ensuring the safety operation of the device, the method and the device can realize the optimal dispatching of the load between the machine sets of the whole plant.

Description

technical field [0001] The invention relates to a method and device for optimal load distribution of a power plant, in particular to a method and device for optimal distribution of plant-level load in a thermal power plant. Background technique [0002] At present, the domestic thermal power plant load distribution adopts the automatic power generation control system direct adjustment method, and the power grid dispatching automatic energy management system directly issues load instructions to each unit controller through the telecontrol terminal according to the customer's load demand. In the current load distribution method, in many cases, the automatic energy management system of power grid dispatching cannot know the equipment operation status of a specific unit. When an emergency occurs in the generator unit, it will cause some accidents that endanger the safe operation. In addition, the current load distribution method cannot realize optimal dispatching of loads among ...
