(Summary) The PM motor has become increasingly popular for many applications. We proposed a novel synchronizing signal sensor-less vector control method without using any machine model parameters to be able to drive any AC motors. The proposed system was able to be easily constructed without any motor parameters. So far, we proposed electric vehicles (EV) driven by induction motor and PM motor using the proposed sensor-less control method. Moreover we developed a prototype Hybrid Vehicle (HV) driven by an AC Synchronous Motor (SM) with a developed an inverter unit. The HV was converted from a general gasoline vehicle, which is MITSUBISHI LANCER Evolution -CN9A. The HV was reconstructed by an IMsynRM (15kW) and SPMSM(10kW), lead acid batteries (300V, 16Ah), and the handmade inverter units using IGBT devices (Generator unit 600V-400A, motor unit 600V-600A). Total weight of the HV is approximately 1,600kg. In this paper, we introduce the development process and features of the HV. Furthermore we report characteristics of IMsynRM that we developed.

(Summary) This paper proposes sensorless sinusoidal driving methods of permanent magnet synchronous motors for fans and pumps by V/f control. The proposed methods are simple methods that control the motor peak current constant by voltage or frequency control, and are characterized by DC link current detection using a single shunt resistor at carrier wave signal bottom timing. As a result of the dumping factor from square torque load characteristics of fan and pump motors, it is possible to control stable starting and stable steady state by V/f control. In general, pressure losses as a result of the fluid pass of fan and pump systems are nearly constant; therefore, the flow rate and motor torque are determined by revolutions. Accordingly, high efficiency driving is possible by setting corresponding currents to q-axis currents (torque currents) at target revolutions. Because of the simple current detection and motor control methods, the proposed methods are optimum for fan and pump motor driving systems of home appliances.

(Summary) Permanentmagnet (PM) motors have become increasingly popular owing to their use in many applications. PM motor drives require rotorposition sensors. Many techniques that do not involve the use of sensors have been developed for estimation the rotor position from voltage and current measurements.We proposed a novel sensorless control system for PM motor drives that did not require position estimation(3). The system can be easily constructed without using any motor parameters. The system works well over a wide speed-control range; from low to high speeds.In this paper, we describe in detail the principle underlying the proposed sensorless control system for PM motor drives and demonstrate the implementation of the system. Further we present experimental results that confirm the feasibility of the proposed control system.

(Summary) In recent years, various types of fault current limiter (FCL) have been developed, because installation of the FCL will bring a lot of benefits to power system operation. Power system controllers based on a concept of Flexible AC Transmission Systems (FACTS) can also be applicable as the FCL with growing power ratings of them. Such FCLs are expected to contribute power system stabilization or power quality enhancement in addition to fault current limitation. Authors have developed a new type of FCL, which consists of a series reactor and a self-commutated voltage source inverter connected in series with a power distribution line by a coupling transformer. In case of a system fault, the FCL will insert a sufficiently large inductance in series with the distribution line by both the series reactor and the inverter, then it will reduce the fault current. On the other hand, the inverter compensates a voltage drop across the series reactor in a standby mode. As a result, the FCL behaves like a negligible impedance in the standby mode. One of the distinctive features of the FCL is a simple configuration because its control strategy does not require an active power source. In addition, inverter voltage rating of the proposed FCL can be reduced by installing the series reactor as compared with other converter-based FCLs. The aim of this paper is to evaluate the operating characteristics of the FCL with both simulation and experimental studies.

(Summary) The power-voltage and current-voltage characteristics of a PV array change with the variation of insolation and temperature. Especially, the output power of a PV-panel block consisting of series-PV modules inevitably goes down due to partial shading caused by peripheral obstacles. This results in the significant reduction of the total output power from the PV power generation system where a couple of PV blocks are parallel to the DC terminal of interactive inverter because of mismatch of the optimum operating voltages between the PV blocks.In this paper, we propose a power convertion system to compensate the output power of a partially shaded PV array. The proposed system can control the output power of the PV array on a PV block basis, which contributes to a more efficient and simpler implementation of the PV power compensation system than that by individual controls of PV modules using DC-DC converters. In addition to that, inverter DC voltage is appropriately controlled so that the maximum output power from the overall PV array can be obtained. And then, the feasibility of the system is investigated and verified from the simulation and experimental results.

(Summary) The output power induced in the photovoltaic modules is influenced by intensity of irradiance and temperature of the solar modules. Therefore it is necessary to estimate the characteristics of PV modules precisely in order to construct a controller of model reference adaptive system and so on. This paper presents an approach to estimate the I=V curves of photovoltaic modules using fuzzy interpolation. The model is composed of data on short circuit current, open circuit voltage and voltage and current of maximum power point under conditions of several different temperatures and high level intensity of the sunshine. The courve fill factor of modules under the above-mentioned conditions can be used instead of maximum power point dates. The remarkable nonlinear curve between voltage and current of PV module is described by three approximating straightlines emplying fuzzy interpolation.

(Summary) 太陽光発電システムが多数台連系された場合に，電圧・電流の不平衡が懸念されている．不平衡が起こると，正相分に加えて逆相分，零相分が発生する．これらは，三相誘導機が接続された交流系統においては誘導機の出力トルクの低下，相配電線では電力損失の増加や電圧低下などの原因となる．対策としては，SVCやアクティブフィルタなどのパワーエレクトロニクス機器(パワエレ機器)に不平衡補償機能を付加して補償することが考えられている．本稿では，不平衡補償をパワエレ機器の増設によって行うのではなく，多数の連系インバータにで抑制する方法を検討したものである．

(Summary) 太陽光発電システムが多数台系統連系されることによる配電線電圧変動が懸念されている．その対策として，これらの太陽光発電システムを積極的に制御して電圧変動抑制を行う手法が提案されている．著者らは，これまで各太陽光発電システムが自端情報に基づいて無効電力制御を行うことによる電圧変動抑制の効果について検討を行ってきたが，太陽光発電システム間に無効電力制御量の格差が発生し，それが原因で電圧変動を抑制しきれないケースが存在することが分かった．それに対して本稿は，コントロールセンタにより配電線各点の情報に基づいた太陽光発電システムの一括制御を行い，その電圧変動抑制効果を検討したものである．

(Summary) 近年，電力系統の短絡容量増大に伴い，故障等によって引き起こされる短絡電流の抑制のための限流技術が注目されている．筆者らはこれまでに電圧形インバータ方式限流器(FCL)について模擬実験に基づく検討を行ってきた．そこで，本方式の限流器に適した電流検出方式に基づく制御系を新たに考案した．電圧形インバータは，ライン電流を検出し，待機時は限流リアクトルでの電圧降下補償，故障時には等価リアクタンス動作を行う．インバータの直流電圧は，PI制御によって位相補正を行うことにより実現している．本稿ではFCLのインバータ直流電圧一定制御の面から実験に基づく評価を行った結果について述べる．

(Summary) 近年，分散型電源の普及に伴い，エネルギー貯蔵装置を組み合わせて管理・運用するローカルネットワーク型エネルギーシステムが注目されている．このシステムが大規模電力系統から自立して運用される場合には，自然エネルギーをエネルギー源の一部に利用するために，電力品質の問題が顕在化してくる．本研究では，常時は上位電力系統と分散型電源を含む小地域ローカル電力システムが協調しつつ電力の需給を行い，必要に応じてローカルシステム内を無停電のまま連系・自立・再連系という一連の動作が実現できる連系装置を開発し，自立可能なローカル電力システムを構築することを目的としている．この一連の動作をシミュレーションで検証を行った．

(Summary) 太陽光発電システムが多数系統連系されることによる配電線電圧変動が懸念されている．その対策として，太陽光発電システムの出力有効電力の低減や系統からの解列などが考えられているが，太陽光発電の出力抑制は設備利用率の面などから得策ではない．そこで本研究では，太陽光発電系統連系インバータに無効電力制御を付加することによる電圧変動抑制を提案する．これにより，出力有効電力抑制や解列が不要になるだけでなく，配電線電圧の高速かつ連続的な調整が可能になることも期待できる．様々なシミュレーション解析の結果，十分な電圧変動抑制の効果を得ることができたので，その結果について報告する．

(Summary) 近年，半導体電力変換装置の普及により高調波障害の例が報告されている．対策として，アクティブフィルタが効果的であるが比較的高価であり，積極的な導入には至っていない．一方，太陽光発電システムの普及が近年急速に進んでおり，夜間など太陽電池出力がない場合，系統連系インバータは空き容量として存在する．<br>これを有効活用する方策として，系統連系インバータの余剰容量をオンラインで評価しつつ，補償の深さを可変とする高調波補償制御システムについて検討した．配電システムの電圧歪みが大きくなる夜間帯に系統連系インバータが空き容量として存在することから，本制御システムは高い補償効果を望むことができる．
