Problems solved by technology

At present, research results at home and abroad pay more attention to the calculation of regional control requirements, and there are few studies on the distribution of regulated power in AGC units. At present, there is no AGC unit control method that combines the real-time measurement system of generator set regulation performance and the particle swarm optimization algorithm.

Embodiment Construction

[0067] The invention is an AGC unit control method based on a real-time measurement system for the adjustment performance of the generator set and a particle group optimization algorithm, and is used for controlling the automatic power generation of the generator set by a grid dispatching center.

[0068] The AGC unit control method comprises the following steps:

[0069] 1) The regulation rate of each AGC unit is obtained through the real-time measurement system of the regulation performance of the generator set; the real-time measurement system of the regulation performance of the generator set can measure the specific performance indicators such as the regulation rate, regulation accuracy and response time of each AGC unit in real time;

[0070] 2) According to the actual adjustment rate of each AGC unit, the controlled AGC units of the whole network are divided into a fast unit group, a slow unit group and a reverse adjustment unit group;

[0071] 3) In the fast generating...

Abstract

The invention relates to a method for controlling an automatic gain control (AGC) set, in particular to the method for controlling the AGC set based on a generator set regulating performance real-time measurement system and a particle swarm optimization algorithm. The method for controlling the AGC set is under a control performance standard (CPS). After an AGC set allocation strategy is improved by using the method, a regulating target of the set having different regulating performances is more definite. A quick set group is in charge of quick load fluctuating quantity in an area, and the advantages of short response time and high regulating speed rate of the quick set group are fully utilized. A main regulating effect can be quite ideal when a load is steady or fluctuates quickly, so a CPS index of a regional power grid can be stable in an acceptable range and at a power grid frequency, a quite good social benefit is obtained, electricity-purchasing cost is minimized, and an excellent economical benefit is obtained.

Description

technical field [0001] The invention relates to an AGC unit control method, in particular to an AGC unit control method based on a generator set regulation performance real-time measurement system and a particle swarm optimization algorithm, which is an AGC unit control method under the CPS (ControlPerformance Standard) standard. Background technique [0002] Due to the fluctuation of grid load, it often happens that power generation and power consumption cannot be balanced synchronously, and this fluctuation will eventually lead to the collapse of system frequency and voltage. The automatic generation control technology AGC (Automatic Generation Control) is an important technical means to realize the real-time balance between power generation and load in the power system, and to ensure the frequency quality and safe operation of the power system. [0003] The entire AGC control process can be divided into two links: the area regulation demand (Area Requirement, AR) calculat...
