Description
电力系统智能控制装置及其实现方法 技术领域 Power system intelligent control device and implementation method thereof
本发明涉及电力系统， 尤其涉及一种电力系统智能控制装置以及一种电力系统 智能控制装置的实现方法。 背景技术 The present invention relates to a power system, and more particularly to an intelligent control device for a power system and a method for implementing an intelligent control device for a power system. Background technique
现有技术中的电力系统智能控制装置 （又称为 "电力系统安全自动装置")， 是 按照不同功能由不同装置实现的原则进行单独配置的， 如图 1所示， 备自投装置独 立配置， 仅用于实现备自投功能； 稳控装置独立配置， 仅用于实现稳定控制功能。 但是上述这种备自投装置、 稳控装置均独立配置的方式由于配置简单， 功能比较单 一， 存在如下弊端： The power system intelligent control device (also referred to as "power system safety automatic device") in the prior art is separately configured according to the principle that different functions are implemented by different devices. As shown in FIG. 1 , the self-injection device is independently configured. It is only used to implement the self-injection function; the stability control device is independently configured and is only used to implement the stable control function. However, the above-mentioned self-injection device and the stability control device are independently configured in a simple manner, and the functions are relatively simple, and the following drawbacks exist:
一、 部分功能重叠但装置设计方法有差异， 难以协调。 例如备自投装置和稳控 装置都需要判断线路检修， 但设计中往往出现备自投装置设置运行压板， 而稳控装 置设置检修压板 （与运行压板意义相反） 的情况， 一方面工作量加倍， 另一方面也 比较容易导致现场运行人员出现误操作的情况； First, some functions overlap but the device design methods are different and difficult to coordinate. For example, the self-injection device and the stability control device need to judge the line maintenance. However, in the design, the self-injection device is often used to set the operation pressure plate, and the stability control device is provided with the maintenance pressure plate (the opposite of the operation pressure plate), on the one hand, the workload is doubled. On the other hand, it is also relatively easy to cause misoperations by field operators;
二、装置数量增加， 导致运行维护工作量加大。例如当变电站现场线路检修时， 需要对备自投装置和稳控装置分别做安全措施， 防止检修试验时导致装置出现不期 望的动作出口或闭锁； Second, the number of devices has increased, resulting in an increase in operation and maintenance. For example, when the substation site line is overhauled, it is necessary to separately make safety measures for the self-injection device and the stability control device to prevent the device from exposing the unexpected action exit or lockout during the maintenance test;
三、 定值数量增加， 且部分定值相同， 定值整定工作量增加。 比如： 备自投装 置和稳控装置的接入模拟量基本相同， 但由于是两套独立的装置， 从而现场接线也 要加倍； 3. The number of fixed values increases, and some of the fixed values are the same, and the fixed value setting workload increases. For example: the access analogs of the standby device and the stability control device are basically the same, but because it is two independent devices, the field wiring is also doubled;
四、 稳控装置和备自投装置之间的协调配合复杂： 稳控装置切除的线路不允许 备自投恢复供电， 因此， 现场独立配置的稳控装置和备自投装置之间必须进行相互 协调， 才能避免备自投装置误动作。 发明内容 4. The coordination between the stability control device and the self-injection device is complicated: the line cut by the stability control device is not allowed to be restored by the power supply. Therefore, the on-site independent configuration of the stability control device and the self-injection device must be mutually Coordination, in order to avoid misuse of the self-injection device. Summary of the invention
为解决上述问题， 本发明提供一种电力系统智能控制装置及其实现方法， 能够 集备自投功能与稳控功能于一体。

An intelligent control device for a power system, comprising: a self-injection unit, a stability control unit, a self-injection and a stability control unit, wherein the stability control unit, the self-injection and stability control unit, and the self-injection unit are sequentially connected. The self-injecting unit is also connected to the stability control unit;
所述备自投与稳控配合单元用于实时监测所述稳控单元， 并判断所述稳控单元 是否有稳控动作， 如果有则闭锁备自投功能。 The standby self-administering and stable control unit is configured to monitor the stability control unit in real time, and determine whether the stability control unit has a steady control action, and if so, lock the self-injection function.
一种电力系统智能控制装置的实现方法， 包括以下步骤： A method for implementing an intelligent control device for a power system includes the following steps:
统一设计电力系统智能控制装置的输入输出， 包括统一设计输入的模拟量和开 入量、 开出量； Unified design of the input and output of the intelligent control device of the power system, including the analog input and the input and output of the unified design input;
进行功能设计， 从过负荷单元、 低频减载单元、 低压减载单元中选择任意一个 或者任意组合作为电力系统智能控制装置的稳控单元； Perform functional design, select any one or any combination of the overload unit, the low frequency load shedding unit, and the low voltage load shedding unit as the stability control unit of the power system intelligent control device;
实时监测所述稳控单元， 并判断所述稳控单元是否有稳控动作， 如果有则将电 力系统智能控制装置中的备自投单元的备自投功能进行闭锁。 The stability control unit is monitored in real time, and it is determined whether the stability control unit has a steady control action, and if so, the standby self-projection function of the standby self-injection unit in the power system intelligent control device is blocked.
本发明的一种电力系统智能控制装置及其实现方法， 由于保证了稳控动作切除 负荷线路后该线路不被备自投单元恢复，从而实现了备自投功能和稳控功能的配合， 真正做到了集备自投功能与稳控功能于一体， 使用一套装置即实现了以往两套装置 才能实现的功能， 减少了施工和维护的工作量， 也减少了由于设计方面的差异所带 来的误操作的可能性， 还减少了定值整定和定值管理的工作量， 降低了稳控单元和 备自投单元之间的协调配合复杂度， 有利于装置的标准化设计和推广使用。 附图说明 The power system intelligent control device and the implementation method thereof of the invention ensure that the line is not restored by the self-injection unit after the power line is cut off by the steady control action, thereby realizing the cooperation between the self-injection function and the stability control function, The utility model integrates the self-injection function and the stability control function, and realizes the functions that can be realized by the previous two devices by using one device, reduces the workload of construction and maintenance, and reduces the difference due to design differences. The possibility of misoperation also reduces the workload of fixed value setting and fixed value management, reduces the coordination and coordination complexity between the stability control unit and the standby self-injection unit, and is conducive to the standardized design and popularization of the device.

现有技术中， 备自投装置和稳控装置都是独立配置的， 只能单独的实现备自投 功能或稳控功能。 两者不仅在设计方法上存在差异 （如前所述的运行压板和检修压 板的设计），在实现其各自的功能时也会给对方产生一定影响，如稳控装置在动作时， 往往需要闭锁备自投装置， 防止备自投装置恢复被切除线路的供电， 导致稳控功能
失效。 因此若想要将备自投功能和稳控功能较好的结合在一起， 必须要解决这个冲 突问题。 In the prior art, the self-injection device and the stability control device are independently configured, and the self-injection function or the stability control function can only be implemented separately. Not only do the two differ in the design method (the design of the running platen and the maintenance platen as described above), but also affect the other side when implementing their respective functions. For example, when the stability control device is in motion, it often needs to be blocked. Prepare the self-injection device to prevent the self-injection device from restoring the power supply of the cut-off line, resulting in stability control function Invalid. Therefore, if you want to combine the self-injection function and the stability control function, you must solve this conflict problem.
本发明提供一种电力系统智能控制装置及其实现方法， 在实现稳控动作时能够 闭锁备自投， 防止稳控失效， 从而将备自投功能和稳控功能较好的结合在一起， 解 决了现有电力系统智能控制装置中配置方式简单、 功能单一的问题。 The invention provides an intelligent control device for a power system and an implementation method thereof, which can lock a self-injection when implementing a steady control action, prevent a control failure, thereby combining the self-injection function and the stability control function to solve the problem. The existing power system intelligent control device has a simple configuration and a single function.
