Precise estimation of synchronized phasors in phasor measurement unit (PMU) is significant for system analysis, control and security. Measurement technique under dynamic conditions is addressed in recent researches. Limitations and criteria for dynamic behaviors are proposed in the new issued IEEE Std. C 37.118-2011 for synchrophasor measurements for power system. In this paper, dynamic characteristics of signals are described as non-stationary signals with amplitude and frequency modulations (AM-FM). A new method for estimating synchronized phasor based on AM-FM demodulation by Energy Operator is presented. In order to avoid the effect of noise, low-pass differentiator is employed. Performance of algorithm is evaluated by simulations and analysis of field data. The result illustrate that the algorithm proposed in this paper improves precision of phasor estimation and reduces response time of PMU, which meets the requirement of the current standard even during dynamic behaviors.
在相量测量单元(PMU)中，同步相量的精确估计对系统分析、控制和安全具有重要意义。动态条件下的测量技术是目前研究的热点。在新发布的IEEE Std. C 37.118-2011中，提出了电力系统同步量测量的限制和动态行为标准。本文将信号的动态特性描述为具有幅频调制(AM-FM)的非平稳信号。提出了一种基于能量算子的调幅调频解调同步相量估计方法。为了避免噪声的影响，采用了低通微分器。通过仿真和现场数据分析，对算法的性能进行了评价。结果表明，本文提出的算法提高了相量估计的精度，缩短了PMU的响应时间，即使在动态行为下也符合现行标准的要求。

Rapid increase of wind power installation in China brings new technical issues and challenges for grid security operation. Reactive power and voltage control capability of wind farms is one of key issues that grid operators concern with. This paper presents a coordinated reactive power and voltage control system for wind farm gird integration to meet operation requirements described in the standard of State Grid Corporation of China “Technical rule for connecting wind farm to power system”. The control strategy of the proposed system takes into account the coordination between voltage and power factor. The proposed system includes two control modes, i.e., schedule voltage tracing mode and optimization mode. To prove the effectiveness of the proposed strategy, a simulation study is first implemented. Based on this, a control system with the proposed control strategy is developed. Then a field test is carried out in Shanghai Fengxian Haiwan Wind Farm to verify the characteristics of reactive power output and voltage tracking of the system. The results demonstrate that technique indices of reactive power and voltage control system (RPVCS) can satisfy the requirements of the standard. It can improve the voltage stability by effective control of reactive power of wind farm.

A rule-based expert system is developed for service restoration of distribution systems. The inference engine for a four-way line switch and other distribution components are proposed to implement proper restoration plan after the faulted location has been identified and isolated. The unfaulted but out of service areas are restored efficiently for multiple contingencies simultaneously. To assure the restoration plan can comply with operation regulation, heuristic rules based on the standard operation procedures of Taipower distribution system are included in the best first search of the expert system. For the fault contingency during summer peak season, the load shedding is executed to restore service to as many key customers and load as possible. The priority indices of each feeder and service zone are defined by the key customers within the service territory. A Taipower distribution system with 18 feeders is selected for computer simulation to demonstrate the effectiveness of the proposed methodology. It is found that the service restoration of distribution system can be obtained very efficiently by applying the proposed expert system.

Information technology played an important role in information and knowledge dissemination in the last decade in the almost all the domains through the development of internet, wireless, satellites and mobile based intelligent knowledge based information system. These systems need timely expert advice to make them more productive and competitive. By implementing them as knowledge servers, it becomes economically feasible, profitable, and beneficial to users to share knowledge. The Indian tariff structure for power generation utilities has also undergone major revision under the ABT regime. As a result, the operation philosophy employed by power generation utilities also has undergone change under the ABT. The proposed solution aims to help the end user (as a large power generation utility) to manage their resources in the most optimal and economic fashion under the new regime. Scheduling implies drawing up a generation program to cater to forecast power demand at a minimum cost subject to transmission system constraints, capability of generating units & other factors (e.g. voltage profile, system security & system sustainability under grid disturbance). Architecture for Optimization of Generator Scheduling under ABT Regime Using Intelligent Agents is proposed involving Tariff modeling engine, Generation scheduling engine, Generation target achievement engine, etc.

Photovoltaic (PV) generations are expected to have an important role in the near future. However, the power output from the PV is random and intermittent in nature. Therefore, the PV generation poses many challenges to the power system operation. To evaluate impacts of the behavior of PV on the power system operation, we have so far proposed effective use of pumped storage hydro power plant (PSHPP). In the previous research, it takes too much computation time to obtain an optimal scheduling of PHSPP. In this paper, a new optimal scheduling method using efficient economic load dispatch (ELD) calculation and using optimal solutions stored in the database is presented.

The electrical loads is the non-stationary time series. With the non-stationary time series, the wavelet technique is more effective technique for approximation. In recent year the fuzzy-wavelet is more attractive for forecasting problem. This paper presented the load curve and electricity consumption forecasting based on MODWT and fuzzy logic. For each individual wavelet sub-series, the fuzzy-rules will be determined in order to carry out the forecasting. After that, the individual wavelet sub-series forecasts are recombined to give the final result.

In this research, the novel hysteresis current controller in dq reference frame is proposed to replace the traditional Proportional-Integral (PI) regulator in the vector control scheme of Doubly Fed Induction Generator (DFIG). More dominant than conventional hysteresis current controller, this algorithm can modulate the voltage space vector directly in the dq rotation frame. Therefore, it is simple to employ the new method in the vector control scheme of DFIG. In addition, it can be used in demagnetizing current control scheme to ride through the grid voltage disturbances. The simulation results demonstrated the very fast dynamic responses of power control and the ride through capability of this method under voltage dips.

Timely bus protection is extremely critical due to the widespread instability of the power system that can occur due to a bus fault. In addition to existing conventional ways of 11 kV bus protection a newer possibility of arc-flash protection using IEC 61850 generic object oriented substation event (GOOSE) messaging is now possible. Arc-flash protection has both high selectivity and security and relatively it costs less with other comparable schemes. This paper describes the design and implementation of Arc-Flash Protection using IEC 61850 based GOOSE messaging at a real substation in New Zealand. Further development and application of this form of 11kV bus protection happening in Powerco will also be discussed.

Multi-level Current Reinjection (MLCR) concept adds self commutation capability to thyristors, and produces a high quality line current waveforms and provides reactive power compensation in current source converters (CSC). Multi-level conversion is applied to generate the required optimum linear multilevel injection current which, when reinjected to the ac side, reduces the line current total harmonic distortion (THD) and forces the thyristor current to be zero. In this paper a comparative study is carried out for a 3-level, 5-level, and 7-level thyristor based MLCR CSC in terms of line current THD obtained, reinjection transformer requirements, reinjection switch ratings, and reinjection control circuitry complexities. Extensive PSCAD/EMTDC simulations are presented for comparing the different m-level reinjection schemes.
