Regarding.

負荷制御装置となっている。As described in Japanese Unexamined Patent Publication No. 59-1.22710, the conventional device is equipped with a general load control unit that collectively controls the loads of multiple axes, a change rate limiter that limits the rate of change of the general load target value, and a change rate limiter that limits the rate of change of the general load target value. The load control device is equipped with a proportional integrator that calculates the load target value for each axis based on the deviation between the output of the rate of change limiter and the sum of the actual outputs of multiple axes.
しかし、下記の点について配慮されていなかった。However, the following points were not considered.

る。In other words, the combined cycle power generation plan l- is said to have good load response, but the response delay due to the exhaust heat recovery boiler is faster than the load response of the boiler in conventional thermal power plants, but no improvements have been made. , there is a response delay in the sum of the actual outputs of multiple axes, which is a feedback signal, with respect to the overall load target value. Furthermore, since the change in the overall load target value is limited by the change rate limiter, the control command value is delayed by the amount limited by the change rate limiter, and as a result, the load The response will be delayed.

っていないという問題があった。In the above conventional technology, there is a delay in the sum of the actual outputs of multiple axes, that is, a feedback signal of the overall actual output, which is caused by a delay in the load response of the waste heat recovery boiler, and a delay in the control output command by the rate of change limiter causes a load There will be a delay in response,
There was a problem in that the overall load control method did not take full advantage of the characteristics of combined cycle power plants, which are said to have good load response.
本発明の目的は、発電プラントとしての負荷応答性を改
善した負荷制御装置を提供することにある。An object of the present invention is to provide a load control device with improved load response as a power generation plant.

ることにより、達成される。The above purpose is to install a subtracter that calculates the deviation between the overall load target value and the overall actual output, and to install a gain multiplier to make the output of the subtracter the optimum signal amount as the preceding control element signal, and to use the overall load target value. However, the overall actual output overshoots,
A monitor relay that detects when the overall actual output approaches the overall load target value to prevent undershoot; a signal generator and switch that zeros the preceding control element by the output of the monitor relay; and an output of the switch. This is achieved by installing an adder that adds the pre-control element signal to each axis load target value.
総括負荷制御部で演算された総括負荷目標値と総括実出
力との偏差は、減算器によって演算する。The deviation between the overall load target value calculated by the overall load control section and the overall actual output is calculated by a subtracter.

より先行制御要素を零とする。When the deviation increases to the positive side, this increase is multiplied by a gain and added to each axis load target value as a preliminary control element, thereby bypassing the rate of change limiter and controlling the overall load target value. In addition to proactive detection, the response delay of the overall actual output is also detected as the deviation, and by proactively increasing the load target value of each axis, the overall actual output can be brought closer to the overall load target value faster than before. can. When the deviation increases to the negative side, by adding it to the load target value of each axis in the same way as when it increases to the positive side, the load target value of each axis is preemptively reduced and the overall load target value is reached faster than before. You can get close. Further, even if the overall actual output approaches the overall load target value, if the preceding control element continues to be added to each axis load target value, overshoot or undershoot may occur. To prevent this, a monitor relay detects that the overall actual output approaches the overall load target value, and a switch sets the advance control element to zero.
