Problems solved by technology

[0004] The automatic power generation control test is mainly divided into two stages: the step load disturbance test and the follow-up load disturbance test. At present, there is no mature test method. To control the test target, there is an urgent need for an automatic power generation control follow-up load disturbance test method

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] The invention provides a thermal power generating set automatic power generation control follow-up load disturbance test method, which can realize the following test functions:

[0027] 1. Check whether the automatic power generation control adjustment rate function is qualified under the unit follow-up test.

[0028] 2. Check whether the automatic power generation control response time is qualified under the unit follow-up test.

[0029] 3. Check whether the dynamic deviation of automatic power generation control is qualified under the follow-up test of the unit.

[0030] 4. Check whether the static deviation of the automatic power generation control is qualified under the unit follow-up test.

[0031] In order to achieve the above test function, such as figure 1 As shown, the automatic generation control follow-up load disturbance test method of t...

Abstract

The invention relates to an automatic power generation control follow-up load disturbance test method for a thermal generator set, which is mainly and technically characterized by comprising the following steps of: setting rated power, an initial load value and a target load value of the thermal generator set, and entering a follow-up load disturbance mode; recording different moments of enteringload change and actual loads at the moment according to an automatic power generation control follow-up disturbance test load change curve; and checking whether the automatic power generation controlspeed regulation function, the control response time, the dynamic deviation and the static deviation are qualified or not under the follow-up test of the thermal generator set. The design is reasonable, the test time is shortened, the risk of unit load fluctuation and equipment outage is reduced, the working efficiency is improved, and scientific guidance can be provided for an automatic power generation control test.

Description

technical field [0001] The technical field of thermal power generation of the present invention relates to a thermal power generation unit disturbance test, in particular to a thermal power generation unit automatic power generation control follow-up load disturbance test method. Background technique [0002] Automatic power generation control technology is a very important technology for generator sets. The control goal of automatic power generation control is to continuously reduce the regional load error due to load changes to zero, to balance the output of thermal power generation units with the grid load by the control center, to maintain the exchange power of the connection line in the region within the planned value range, and to reduce the regional operating cost. At the same time keep the grid frequency stable. [0003] With the continuous upgrading of the "two detailed rules" of the power grid, the platform has increased requirements for the quality assessment of ...
