Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of phase regulator control, and in particular to a monitoring method and system for an intelligent integrated monitoring system of a phase regulator. Background Art
[0002] In the power grid, the electric power supplied to the load by the power supply is divided into active power and reactive power. The active power is used to start the normal operation of the equipment. However, due to the existence of inductive or capacitive reactance characteristics of the equipment, the alternating current will have self-inductance in the power grid, resulting in power waste. This not only wastes electric energy, but also causes unstable grid voltage, or circuit overload or other situations. For this reason, people usually set up capacitive and inductive reactance devices with opposite effects to offset them. This is the origin of the phase regulator. In the prior art, there are also control and detection systems for phase regulators, and corresponding abnormal detection technologies for medical insurance, such as:
[0003] Patent application CN112036601A discloses a method for predicting the oil temperature of a synchronous condenser oil system, which belongs to the technical field of synchronous condensers and mainly includes the following steps: (1) calculating the comprehensive correlation of historical samples; (2) selecting similar days to the day to be predicted; (3) calculating the oil temperature of the synchronous condenser oil system on the day to be predicted based on the extrapolation weighting of similar days. The method calculates the comprehensive correlation between historical samples and the day to be predicted based on three factors: meteorology, time and events. According to the comprehensive correlation, the method selects similar days to the day to be predicted from the two aspects of the actual oil temperature and temperature change rate of the synchronous condenser. At the same time, the oil temperature is predicted by using a neural network and a trend change method respectively, and the two prediction results are weighted based on the correlation, which effectively ensures the prediction accuracy of the oil temperature of the synchronous condenser oil system, realizes the real-time monitoring of the oil temperature of the synchronous condenser oil system, and provides strong support for the safe operation of the synchronous condenser.
[0004] Patent application CN110782190A discloses a phase shifter remote diagnosis system based on ubiquitous power Internet of Things technology, including equipment ledger database, standard database, historical database, evaluation model database, fault diagnosis model database, remote expert diagnosis database, online monitoring equipment, workflow engine, communication device, and management server. The present invention uses the power grid as a hub, builds a data center through data warehouse and data replication technologies, and realizes the sharing and exchange of all information data; realizes the processing of abnormal values, data standardization, data generalization and data aggregation through data conversion, and then realizes the reasoning work of the fault diagnosis knowledge base; uses data warehouse and data mining technology to perform integrated indicator analysis on various indicators in the operation, production, and management of the phase shifter, and establishes a safety early warning evaluation system based on massive data, which can combine the system operation status estimation technology to ensure the healthy operation of the phase shifter and realize refined prediction and coordinated control.
[0005] Patent application CN109586311A discloses a coordinated control method for a phase regulator and a reactive compensation device of a DC converter station, which mainly includes proposing a coordinated cooperation scheme for the phase regulator and the DC, as well as a coordination strategy under normal operating conditions of the power grid and a coordinated cooperation strategy under conditions such as faults. The results show that under the coordinated cooperation strategy, the transient reactive support effect of the phase regulator is improved, thereby improving the stability level of the power grid voltage and reducing the probability of DC commutation failure, that is, improving the safe and stable operation level of the UHV power grid.
[0006] Patent application CN109149594A discloses an optimization method for non-full-phase operation of a DC receiving-end phase condenser, including: if a local non-full-phase signal is input and the current at the machine end of the modulation group and the high-voltage side of the main transformer does not meet the non-full-phase protection judgment condition of the modulation group, a non-full-phase reactive power command signal is sent to the phase condenser monitoring system; the reactive output of the phase condenser is increased; if the reactive output of the phase condenser meets the judgment condition of the non-full-phase protection of the modulation group and the non-full-phase protection of the modulation group has not yet been activated, the phase condenser monitoring system will keep the phase condenser in reactive output operation that meets the judgment condition of the non-full-phase protection of the modulation group. The present invention avoids the problem that the existing DC receiving-end phase condenser modulation group has a non-full-phase state of the phase condenser under low reactive output, which makes the phase condenser continue to operate in a non-full-phase fault state, and prevents the phase condenser from being strongly excited and instantly outputting a large amount of reactive power in a non-full-phase fault state. The huge negative sequence current generated by the phase condenser causing huge damage to the phase condenser rotor and reducing the operating life of the phase condenser.
[0007] Patent application CN109038684A discloses a method for idling synchronous grid-connected large-scale synchronous phase-converting units, including: using an SFC device to drag the phase-converting unit, when the speed of the phase-converting unit is accelerated to 1.05 times the rated speed, the SFC device exits and the excitation system boosts the voltage; the phase-converting unit is affected by mechanical friction, no-load loss of the main transformer and excitation loss, and the speed gradually decreases. After the monitoring system detects that the voltage at the machine end rises to the set value, it sends a start synchronization command to the synchronization device. The synchronization device detects the voltage on the side to be connected and the grid side for real-time calculation, captures the grid-connected opportunity during the idling process of the unit, and sends a grid-connected circuit breaker closing command when it is determined that the conditions for synchronization are met; after detecting the grid-connected circuit breaker closing signal, the synchronization device feeds back a synchronization success signal to the monitoring system, and the synchronization grid-connected is successful. The present invention can realize the rapid and reliable grid-connected connection of the synchronous phase-converting unit, and has guiding significance for the synchronous grid-connected connection of other similar idling equipment.
[0008] Patent application CN105785188A discloses a phase adjustment test method for a large-capacity phase regulator with less impact on the power grid. It is proposed that when the phase adjustment test of the phase regulator is carried out, it should be carried out under the condition that two phase regulators on the same bus are running simultaneously. When one phase regulator is carrying out the lagging phase test, the other is carrying out the leading phase operation test. In this way, the phase regulator of the leading phase test provides a power grid environment with a low power grid voltage for the phase regulator of the lagging phase test. Similarly, the phase regulator carrying out the lagging phase test provides a power grid environment with a high power grid voltage for the phase regulator of the leading phase test. This avoids the phase regulator machine terminal voltage reaching the lower limit due to insufficient grid voltage during the leading phase test or the machine terminal voltage reaching the upper limit due to insufficient grid voltage during the lagging phase test. The present invention enables the phase regulator to obtain the desired phase adjustment performance through the test, and at the same time reduces the impact on the grid voltage to a certain extent during the test, and has good application prospects.
[0009] However, the following technical problems still exist in the current phase regulator and its use:
[0010] 1. In the prior art, when the power grid is phase-adjusted, a phase regulator is usually used. However, when electricity is applied, the activation and deactivation of the electrical equipment is intermittent, that is, it is activated at a certain time and deactivated at another certain time, which causes the capacitive reactance and inductive reactance characteristics in the power grid to be variable. Therefore, if only a fixed phase regulator is used, it is easy to lead to a situation where it can only meet the requirements for a certain period of time and does not meet the requirements for most of the time, which may have the opposite technical effect.
[0011] 2. In the transmission network, usually certain power nodes are connected in a network. With this topology, if in the advanced power nodes, although a relatively low capacitance or inductance value is maintained overall, the capacitance value is relatively high in each lower power node, which may easily lead to a large amount of useless work required in each lower power node, resulting in voltage instability or an accident due to overload of the main cable.
[0012] 3. For the power grid, there may be irregular sudden large-power consumption equipment or power consumption nodes. If only the fitting method based on historical power consumption data is adopted, it will be impossible to handle the sudden power consumption data of the emergency. The sudden impact on the power grid will easily lead to errors in the transmission network.
[0013] In the face of the above technical problems, people hope to provide a more intelligent, more convenient and more accurate regulator system, so as to better and quickly adapt to the power supply needs of the power grid. However, so far, there is no effective way to solve the above technical problems in the existing technology. Summary of the invention

[0020] According to the maximum capacitive reactance value and the maximum inductive reactance value of each power consumption node, the maximum inductive reactance value and the maximum inductive reactance value of the phase regulator of each power consumption node are configured so as to cover the phase regulation of all power consumption scenarios;
[0021] When the intelligent integrated monitoring system for phase regulators is working, the intelligent phase regulation centralized control platform forms phase regulator control instructions for each power consumption node based on the corresponding relationship between the capacitive reactance value and time, and the phase regulator control instructions include the configured reactance value and the operation time, and are sent to the phase regulator startup module. The phase regulator startup module configures the corresponding reactance value capacitor or inductor at the corresponding operation time based on the corresponding phase regulator control instruction obtained; at the same time, the data acquisition module acquires the reactance value of each power consumption node at the real time, and sends the reactance value of each power consumption node at the current moment of the position of the power consumption node to the intelligent phase regulation centralized control platform of the phase regulator.

[0022] Preferably, the data acquisition module collects the reactance value of each of the power nodes at the real-time moment, and sends the reactance value of each of the power nodes at the current moment of the position of the power node to the intelligent phase-adjusting centralized control platform of the phase regulator. The intelligent phase-adjusting centralized control platform is based on the reactance value of each of the adjacent power nodes at the same level connected to the same upper-level power node. When the reactance values of each of the power nodes are basically matched, the power nodes of the upper-level power nodes are not connected to the phase regulator.
[0023] Preferably, the intelligent phase-shifting centralized control platform obtains the active power and reactive power collected by the electricity consumption meter, and then obtains the reactive power ratio of the electricity consumption node. When the reactive power ratio is lower than a preset value, the phase-shifting start-up module shuts down the use of the phase-shifting module.

[0026] Preferably, the data acquisition module collects the reactance value of each power consumption node at real time. After the phase modulator module is enabled by the phase modulator startup module, if the reactance value is still higher than the preset value, it is considered that the phase modulator is faulty and an alarm is issued through the intelligent phase modulation control platform.
